Question
Choose the correct answer from the options given below
To increase the pH value of a neutral solution, we should add:
1) an acid
2) an acid salt
3) an alkali
4) a salt
Solution
an alkali
The lower range of pH scale (1 to 6) represents acidic nature, while upper range of pH scale (8 to 14) represents alkaline nature. Therefore, to increase the pH value of a neutral solution (pH = 7), we should add an alkali.
