. Answer the following questions in brief:1. Name any two mineral acids and two organic acid2. 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. 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.
