Distilled water is neutral. You can verify this by using litmus paper: red litmus paper will remain red, and blue litmus paper will remain blue when dipped into distilled water. Alternatively, a pH meter will show a reading of approximately 7.
Explanation:
Litmus Test:
Litmus paper is an acid-base indicator. Red litmus paper turns blue in the presence of a base (basic solution) and blue litmus paper turns red in the presence of an acid (acidic solution). If the solution is neutral, neither litmus paper will change color.
pH Meter:
A pH meter measures the acidity or basicity of a solution using a pH scale. Distilled water has a pH of 7, which is considered neutral.
