Answer 1

ANSWER:-

◆ PROPERTIES OF ACIDS

1. The term 'ACID' has been derived from tje Latin word, 'ACIDUS' which mean sour.

2. Acids have sour in taste.

3. They turn blue litmus into red.

4. They give H+ ions in aqueous solution.

◆ When metal react with acids to give hydrogen gas and salt.

Metal + Acid ---- Hydrogen gas + salt.

◆ EXAMPLE

Zn + H2SO4 --- ZnSO4 + H2

where Zn (Zinc) is metal and H2SO4 (Sulphuric acid) is acids.

◆ Metal in this above reaction displaces hydrogen from the acids. This seen hydrogen gas. The metal combines with the remaining part of the acid and forms a compound called a salt.

◆ Hydrogen gas released can be tested by bringing burning candle near the gas bubbles, it burust with pop sound so, hydrogen gas will release.
