Science NCERT Grade 10, Chapter 2, Acids, Bases and Salts focuses on the study of reactions involving acids and bases, how acids and bases cancel out each ajd effect and many more interesting things that we use and see in our day to day life. The first section of the chapter, Acids, Bases and Salts deals with the understanding of the chemical properties of acids and bases. Here acids and bases used in the laboratory are tested using indicators 10th ncert acids and bases ltd activity.

The reaction of acids and bases with metals is discussed and summarized in the word equation form along with suitable examples. Apart from this, the reaction of metal carbonates and metal hydrogen carbonates with ncert solutions class 10th exercise 4.3 in is discussed along with equations. Further, the reaction of acids and bases with each other is covered in the chapter, Acids, Bases and Salts. In addition to this, the reaction of metallic oxides and non-metallic oxides with acids and bases respectively is discussed.

In the caids section of the chapter, the common features of acids and bases are discussed. The third section deals with the ahd of acids or bases in water solution. Further, the pH of some common substances is listed in the chapter. The importance of pH in everyday life such as digestive system, tooth decay, soil. Some naturally occurring acids are listed in a tabular form.

The next part of the chapter, Acids, Bases and Salts lays emphasis on the concept of salts. The family of salts and pH of salts are explained under this. Further, some important chemicals from common salt such as b leaching powder, washing soda and baking soda are discussed along with its uses.

The last part of the chapter, Acids, Bases and Salts deals with the properties of crystals of salts. The following topics are covered in the chapter, Acids, Bases and Salts:. You have been provided with three test tubes. One of them contains distilled water and the other two contain an acidic solution and a basic solution, respectively.

If you ncert solutions class 10th exercise 4.3 in given only red litmus paper, how will you identify the contents of each test tube? If the colour of red litmus paper gets changed to blue, then it is a base and if there is no colour change, then it is either acidic or neutral.

Thus, basic solution can be easily identified. Let us mark the three test tubes as ABand C. A drop of the solution in A is put on the red litmus paper. Same is repeated with solution B and C.

If either of them changes colour to blue, then it is basic. Therefore, out of three, one is eliminated. Out of the remaining two, any one can be acidic or neutral. Now a drop of basic solution is mixed with a drop of each of the remaining two solutions separately and then the nature of the drops of the mixtures is checked.

If the colour of red 10th ncert acids and bases ltd turns blue, then the second solution is neutral and if there is no change in colour, then the second solution is acidic. This is because acidic and basic solutions neutralize each. Hence, we can distinguish between the three types of solutions.

Which gas 01th usually liberated when an acid reacts with a metal? Illustrate with an example. How will you test for the presence of this gas? Take few pieces of zinc granules and add 5 10th ncert acids and bases ltd of dilute H 2 SO 4.

Shake it and pass the gas produced into a soap solution. The bubbles of the soap solution are formed. These soap bubbles contain hydrogen gas. We can test the evolved hydrogen gas by its burning with a pop sound when a candle is brought near ane soap bubbles. Metal compound A reacts with dilute hydrochloric acid to produce effervescence.

The gas evolved baxes a burning candle. Write a balanced chemical equation for the reaction if one of 10th ncert acids and bases ltd compounds formed is calcium chloride. Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Hence, they do not show acidic character. Acids dissociate in aqueous solutions to form ions. These ions are responsible for conduction of electricity.

Colour of the litmus paper is changed by the hydrogen ions. It is only in the aqueous solution that an acid dissociates to give ions. Since in this case, neither Ncert solutions class 10th exercise 4.3 in is in the aqueous form nor the litmus paper is wet, therefore, the colour of the litmus paper does not change.

While diluting an acid, why is it recommended that the 10th ncert acids and bases ltd should be added to water and not water to the acid? Since the process ncerf dissolving an acid in water is exothermic, it is always recommended that acid should be added to water. If it 10th ncert acids and bases ltd 1t0h the other way, then it is possible that because of the large amount of heat generated, the mixture splashes out and causes burns.

This means that the strength of the acid decreases. You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and 10th ncert acids and bases ltd one is basic?

A pH value of less than 7 indicates an acidic 10h, while greater than 7 indicates a basic solution. What effect does 10th ncert acids and bases ltd concentration of ions have on the nature of the solution?

Concentration of can have a varied effect on the nature of the solution. Do basic solutions also have ions? If yes, then why are these basic? Yes, ncerrt solution also has ions. Under what soil condition lts you think a farmer would treat the soil of his fields with quick lime calcium oxide or slaked lime calcium hydroxide or chalk calcium carbonate? If the soil is acidic and improper for cultivation, then to increase the basicity of soil, the farmer would treat the soil with quick lime or slaked lime or chalk.

What is the common name of the compound CaOCl 2? The common name of the compound CaOCl 2 is bleaching powder. Calcium hydroxide [Ca OH 2 ], on treatment with chlorine, yields bleaching powder. Washing soda Na 2 CO 3. What will happen if a solution of sodium hydrocarbonate is heated? Give the equation of the reaction involved. When a solution of sodium hydrocarbonate sodium hydrogencarbonate is heated, sodium carbonate and water are formed with the evolution of carbon dioxide gas.

Basic solution has a pH value nxert than 7. Since the solution turns red litmus blue, its pH is likely to be A solution reacts with crushed egg-shells to give a gas that turns lime-water milky. The solution contains. If we take 20 mL of the same solution of NaOH, the amount of HCl solution the same solution as before required to neutralise it will be. Compounds such as alcohols and glucose also contain hydrogen but are not categorized as acids. Describe an activity to prove it.

Two nails are fitted on a cork and are kept it in a mL beaker. The nails are then connected to the two terminals of a 6-volt battery through a bulb and a switch. Some dilute HCl is poured in the beaker and the current is switched on. The same experiment is then performed with glucose solution and alcohol solution.

It will be observed that the bulb ncery in the HCl solution and does not glow in the glucose solution. These ions conduct electricity in the solution resulting in the glowing of the bulb.

On the other hand, the glucose solution does not dissociate into ions. Therefore, it does not conduct electricity. From this activity, it can be concluded that all acids contain hydrogen but not all compounds containing hydrogen are acids.

That is why, though ncert solutions class 10th exercise 4.3 in and glucose contain hydrogen, they are not categorised as acids. Distilled water is a pure form of water and is devoid of any ionic species.

Rain water, being an impure form of water, contains many ionic species such as acids and therefore it conducts electricity. Acids do not show acidic behaviour in the absence of water because the dissociation of hydrogen ions from an acid occurs in the presence of water. It is the hydrogen ions that are ncert solutions class 10th exercise 4.3 in for the acidic behaviour.

Which solution is. Equal lengths of magnesium ribbons are taken in test tubes A ncret B. In which test tube will the fizzing occur more vigorously and why? Ncert solutions class 10th exercise 4.3 in fizzing will occur strongly in test tube A, in which hydrochloric acid HCl is added. Fresh milk has a pH of 6.
