Buffering agent - Wikipedia, the free encyclopedia

A buffering agent adjusts the pH of a solution. The function of a buffering agent is to drive an acidic or basic solution to a certain pH state and prevent a change in this pH. Buffering agents have...

Practical uses of buffer solutions

Buffer solutions as we have seen are extremely effective at minimising changes in pH, we have commented on their ability to stabalise pH at any range, depending on the pKa value and the concentrations of the acid and base used.

Buffer solutions in action

Steps to calculate change in pH of buffer solution ... First we need to calculate the initial amounts of the acid and base present in the buffer solution and the amount in moles of HCl added. To do this we use ... On the next page we will investigate the uses of buffer solutions in a variety of different environments.
