Question

Write the characteristics of acids by which we can identify acids.

Answer 1

Answer:

Acids taste sour while bases taste bitter. An acid reacts with metals to produce bubbles of hydrogen gas while a base feels slimy to the touch. Acids turn blue litmus paper red while bases turn red litmus paper blue.

Answer 2

The characteristics of acids by which we can identify acids are as follows-

• Acids tend to donate hydrogen ions during a reaction. So, counting the number of ions before and after a reaction can help in identification.
• An acidic material will turn a blue litmus paper red and has a sour taste.
• On reacting with metals, acids release hydrogen as a by-product.
• It is capable of conducting electricity as well and has a pH of less than 7.
