Q. Determine Equilibrium Constants for Acid and base?
Ans.
The pH scale of acidity is a simple and convenient way to state the acidity of a solution.
The pH of acid solutions is less than 7.0. The pH of basic solutions is greater than 7.0. The pH of a neutral solution (for example, pure water) is equal to 7.0.
The pH of a solution is calculated from the concentration of hydrogen ions in a solution:
pH = -log [H+]
For example, if the concentration of H+ is 1 x 10-3 M, the pH is -log(1x10-3) = 3.
