Question

. Answer the following questions in brief:
1. Name any two mineral acids and two organic acid
2. What is the use of litmus paper?
3. Name a base that is used as an antacid.
4. Name three common indicators.
5. What happens when an acid reacts with a base?​

Answer 1

1. MINERAL ACID-Sulphuric acid,HCL

ORGANIC ACID-Malic acid,Citric acid

2. The main use of litmus is to test whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple.

3.Magnesium hydroxide

Magnesium hydroxide ( Milk of Magnesia) is used as an antacid.. Mg(OH)2 is a base used in antacid.

4. The three most common indicators are: Litmus, Methyl orange and Phenolphthalein.

5.When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.

Answer 2

Hello friend,

Your answer goes here

1. Mineral acids: carbonic acid, nitric acid.

Organic acids: citric acid, lactic acid

2. Litmus paper is an indicator which is used for determining  wether a substance  is an acid or base.

3. Milk of magnesia is a base used as an antacid.

4. Hibiscus(china rose), Turmeric(Haldi) Litmus from lichens

5. When an acid reacts with a base heat and water vapour is released, salt is formed and both neutralize the effect on each other. The salt may acidic neutral or basic.

Hope it helps,

Thanks
