Question

pH value of an acidic solution is
1. <7
2. >7
3. 7
4. 0

Answer 1

Correct Answer - Option 1 : <7

The correct answer is <7.

• The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it's possible to get a pH below 0 or above 14.
  • Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

•  Acids taste sour, react with metals, react with carbonates, and turn blue litmus paper red.
  • Bases taste bitter, feel slippery, do not react with carbonates, and turn red litmus paper blue.
  • Usually, acids can be divided into three major types.
  • The\ first one is binary acid, the second one is oxyacid, and the last one is a carboxylic acid.
