How would you determine the pH of a solution?

pH is a measure of acidity and alkalinity. In fact, pH is a logarithmic scale from 0 to 14, with 0 being acidic and 14 being alkaline. When there is a high concentration of H+ ions then the solution is acidic and the pH=0. If there is a low concentration of H+ ions then the solution is alkaline and the pH=14. To calculate the pH use the below formula:pH=-log10[H+] If the pH of the solution is known, then the concentration of H+ ions can be calculated using the following formula:[H+]=10-pH
