Questions Related to introduction to acid and base

The reaction of the acid and the ________ produces carbon dioxide, which causes dough and batters to rise.

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. baking soda

  2. washing soda

  3. sodium hydroxide

  4. ammonium hydroxide

Show answer
Correct Option: A
Explanation:

Baking soda, known by chemists both as sodium bicarbonate and sodium hydrogen carbonate, is another example of a base with multiple purposes. The reaction of the acid and the baking soda produces carbon dioxide, which causes dough and batters to rise.

The acidic behavior of lakes and oceans can be neutralized by:

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. $NaOH$

  2. $HCl$

  3. $CaCO _3$

  4. $Ca(OH) _2$

Show answer
Correct Option: C
Explanation:

Lakes and oceans can become acidic due to acid rain. This increases the acidity of such bodies and affects the aquatic life. To neutralize this acidic behavior of lakes and oceans, calcium carbonate $(CaCO _3)$ is used.

Toothpaste is _________  in nature.

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. acidic

  2. basic

  3. neutral

  4. Both (A) and (B)

Show answer
Correct Option: B
Explanation:

The pH in our mouth is 5.5 which is slightly acidic. If the pH in our mouth decreases it results in tooth decay due to formation of certain acids. Toothpaste is basic in nature which neutralizes the acid and protects from tooth decay.

In which of the following, neutralisation reaction takes place?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Treatment of acid or basic salt

  2. Treatment of acidic effluents

  3. Treatments of gastic patients

  4. All of the above

Show answer
Correct Option: D
Explanation:

Treatment of gastric patients, treatment of acidic effluents from factory wastes and treatment of acid/base salts, are examples of neutralization in everyday life. Hence, D

If the soil is basic the plant do not grow proper, what should we add to it to improve its quality?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Slaked lime

  2. Quick lime

  3. Urea

  4. Organic matter

Show answer
Correct Option: D
Explanation:

To improve the quality of a basic soil, an acid should be added. Slaked lime ($ Ca{ (OH) } _{ 2 } $) and quick lime ($ Ca{ O }$) are basic in nature. Urea is neutral. Hence, organic matter is the answer.

Remedies of which of the following are examples of neutralisation in everyday life?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Ant sting

  2. Indigestion

  3. Factory wastes

  4. None of these

Show answer
Correct Option: A,B
Explanation:

The venom of ant sting is acidic in nature, which is neutralised by the application of alkali like sodium bicarbonate. Indigestion happens due to over production of hydrochloric acid in stomach, which is neutralised by an antacid which is alkali in nature. These are examples of neutralisation in everyday life.

For the growth of plants which of the following top soil is suitable the most:

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Clay soil

  2. Black soil

  3. Loam soil

  4. Sandy soil

Show answer
Correct Option: C
Explanation:

Loam soil is considered ideal for gardening and agricultural uses because it retains nutrients well and retains water while still allowing excess water to drain away.

Honey bee stings and ant bites can be _________ using alkaline medicine such as baking powder.

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. acidifies

  2. neutralize

  3. prevented

  4. none of the above

Show answer
Correct Option: B
Explanation:

The venom of honey bee and ant bites are acidic in nature. So, it's effects can be neutralised by bicarbonate of soda such a baking soda or an alkali (basic in nature). 

Why bee strings are treated by alkaline solutions?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Because it is basic in nature.

  2. Because it is acidic in nature.

  3. Because it is treatable by only alkaline solution.

  4. None of these.

Show answer
Correct Option: B
Explanation:

The venom of a honey bee is acidic in nature. 


So, it's effects can be neutralised by bicarbonate of soda such a baking soda or an alkali (basic in nature). 

Hence the option B is correct.

Using toothpaste in daily life is the example of _________.

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. acidic reaction

  2. basic reaction

  3. neutralization reaction

  4. none of these

Show answer
Correct Option: C
Explanation:

Toothpaste is slightly basic is nature (pH ~ 8). The acid produced on the tooth enamel (commonly known as acid erosion) is neutralised by the toothpaste, cleaning your teeth. Hence, usage of toothpaste is the example of a neutralisation reaction.
