To calculate the pH (potential of hydrogen) of a solution, you can use the following formula:
pH = -log[H+]
Where:
- "pH" is the measure of acidity or alkalinity.
- "[H+]" represents the concentration of hydrogen ions (protons) in the solution.
Here's how you calculate it step by step:
Measure the concentration of hydrogen ions ([H+]) in moles per liter (Molarity, M) in the solution. You might need to use a pH meter or a chemical analysis to determine this value.
Take the negative logarithm (base 10) of the concentration of hydrogen ions:
pH = -log[H+]
Calculate the pH value using the obtained [H+] value.
Remember that pH is a logarithmic scale, so a change of one unit in pH represents a tenfold change in the concentration of hydrogen ions. pH values range from 0 (highly acidic) to 14 (highly alkaline or basic), with 7 being neutral (pure water).
If you're given the hydrogen ion concentration, you can plug it into the formula to find the pH of the solution.
