Question

Write a short note on pH of a solution.

Hint:

pH is a logarithmic scale where a decrease in one unit means a tenfold increase in acidity.

Answer 1

The pH of a solution measures its acidity or alkalinity on a scale of 0 to 14. A pH value below 7 indicates an acidic solution, a pH of 7 is neutral, and a pH above 7 indicates a basic solution. The pH is determined by the concentration of hydrogen ions (\( H^+ \)) in the solution.
