Explanation:

• pH is defined as a measure of acid or alkaline level in the water and it indicates the amount of hydrogen molecules in the water.
• pH value ranges from [0-14], for acidic components pH<7 and base pH>7 and for neutral pH=7.
• Litmus paper measures the pH values and for acid the color of litmus paper changes from blue to red.
• For base solutions, the color changes from red to blue.
• Alkaline solutions change the pH value from red to blue, when it is dissolved in water.

Answer 2
