This simple apllication will offer you methods of preparation of buffers for a given pH. Buffer is a small program that accepts a valid pH value and returns one or more methods of preparation of suitable buffers and a number of pH-indicators that change colors close to the pH value entered.

Theoretical buffer pH and real buffer pH are usually two different numbers. To ensure best accuracy, you are highly recommended to use a pH meter. While monitoring the solution's pH, small amounts of either HCl or NaOH in dilute solution are added until the pH reaches the desired value.
