Which of the following statements are correct?
1 Acid turns blue litmus red.
2 Base turns red litmus blue.
3 Both A and B correct
4 Water changes the colour of red litmus.
Explanation:
Both A and B correct An acidic solution turns blue litmus red. On the pH scale, acids have values less than 7. A basic solution turns red litmus blue. On the pH scale, bases have values more than 7. Water is neither acidic nor basic, which means it is neutral. So, it can not change the color of litmus paper. The pH value for water is equal to 7.
