NCERT Exercise Questions with Solutions

Q.1 Three test tubes, each of them containing distilled water, an acidic solution, or a basic solution, are used to help in the identification of the solutions. Also, red and blue litmus papers are being used to achieve the same objective.

Answer:

Insert the red litmus paper into all the test tubes:

The solution of changing a red litmus into a blue one is the basic solution.

First and foremost, take the blue litmus paper (which has been already made by you) and immerse it into the various solutions from the experiment. The solution which changes the blue litmus back to its original red color is the acid.

A different solution which will not affect the litmus paper in any way, that is, it will not turn it blue or red, is a neutral one, and hence it is distilled water.

Q.2 What is the cause for not keeping curd and sour foods in brass or copper containers?

Answer:

Curd and sour foods have acids that when exposed to brass or copper produce salts of the metal that are harmful. Such compounds can cause food poisoning and hence be a health risk.

Q.3 What is the gas that is produced during the acid-metal reaction?

Answer:

Hydrogen gas (H₂) is liberated during the reaction between acid and metal.

For example:
Zinc + Hydrochloric acid = Zinc chloride + Hydrogen
Zn + 2HCl = ZnCl₂ + H₂↑

Q.4 When metal compound A reacts with dilute hydrochloric acid gas, the extinguishment of a burning candle and the inhalation of the gas is observed. Calcium chloride is one of the by-products. Which compound A do you think it is, and what is the balanced chemical equation for such a reaction?

Answer:

The gas that a candle gives off when extinguished is carbon dioxide (CO₂), and therefore, it is confirmed that a carbonate is produced in the reaction. One of the products is calcium chloride, which then suggests that compound A is calcium carbonate (CaCO₃).

Balanced Chemical Equation:
CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Q.5 How come acids such as HCl and HASO_3 exhibit acidic characteristics in water, whilst alcohol and glucose do not?

Answer:

HCl and HNO₃ are kinds of acids that give off hydrogen ions (H⁺) when dissolved in water.

Q.6 What is the reason for the conduction of electricity through acid aqueous solution?

Answer:

The ionization of acids in solution forms ions (H⁺ or H₃O⁺) and it is these ions that carry the electrical current. Hence, in water, acid solutions are able to conduct electric current.

Q.7 Why is the dry HCl gas incapable of performing the color change of the dry litmus paper?

Answer:

Without the presence of water, the dry HCl gas cannot ionize and consequently, no H⁺ ions are produced. The latter are the ones that contribute to the acidity of the gas, hence the dry HCl does not perform the color change of the litmus paper.

Q.8 What is the reason for always adding acid to water during dilution instead of water to acid?

Answer:

Acid dilution is an exothermic reaction.

The adding of acid to water will result in a gradual and safe release of heat.

Contrary to this, the adding of water to acid may result in instant heat release, thus, causing splashing and burns.

Q.9 What happens to the concentration of hydronium ions (H₃O⁺) when acid is diluted?

Answer:

Dilution results in a decrease of hydronium ions (H₃O⁺) concentration per unit volume, which makes the solution less acidic.

Q.10 What effect does the dissolving of an excess base in water have on hydroxide ion (OH⁻) concentration?

Answer:

In the event of a primary alkaline solution which is afterwards watered down with water, the amount of hydroxide ions (OH⁻) in each unit of volume reduces.

FAQs

1. What detailed explanations do the NCERT Solutions give regarding pouring baking soda into milk and its influence?

NCERT Solutions for Class 10 Science suggest that when baking soda (sodium hydrogen carbonate) is mixed with milk, the pH of the resulting mixture will be above 7. This results in slow curdling as milk can still absorb more acid before getting sour. Thus, the entire concept is presented through practical life instances to ensure better understanding.

2. What is the importance of studying pH in daily life, as told by the NCERT Solutions?

Researching pH in daily life is a good method to figure out how acidic or basic a substance is. The NCERT Solutions pointed out the importance in the following fields:

• Agriculture (soil pH checking),
• Health (antacids use),
• Environment (acid rain),
• Industry and water treatment.
• pH control is necessary for a healthy life and practical applications.
