Buffers Usually Consist Of A Weak Acid And Its Conjugate Base, In Relatively Equal And Large Quantities.

An introduction to ph and buffer solutions calculations [work in progress] code: Another example of calculating ph of a soluti. In chemistry, ph is a measure of the hydrogen ion (h +) concentration in a solution.

Therefore, The Ph Of The Buffer Solution Is 7.38.

It ranges from 0 to 14, with 7 being neutral and values above 7 indicating alkaline solutions, and values below 7 indicating acidic solutions. There is a minute change in its ph when a little or medium amount of strong base or acid is added to it and that is why it is used to avoid changes in the ph of a solution. Ph is defined as the negative logarithm of the hydrogen ion concentration in a solution;
