Q1:

What is the pH of distilled water ?

A 0

B 1

C 7

D 14

ANS:C - 7

The pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is considered neutral, indicating a balanced concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻). Distilled water, being a pure form of water, has neither acidic nor basic properties, so its pH is exactly 7, making it neutral.
