Answer 2

pH paper is used to determine the pH of water obtained from different sources.

• pH determines the acidity or basicity of a substance.
• pH paper has a scale from 1 to 14.
• Below 7 in pH paper is the acidic range and as the pH value decreases acidity increases.
• Above 7 in pH paper is the basic range and as the pH value increases basicity also increases.
• 7 is the neutral range.
• Water is a neutral liquid. So, it has pH around 7.
