A buffer solution has to contain. This chemistry video tutorial explains how to calculate the ph of a buffer solution using the henderson hasselbalch equation. A buffer solution is one in which the ph of the solution is resistant to small additions of either a strong acid or strong base.
ph of buffer solution equation
Ph calculation lectures ph of a buffer the henderson hasselbalch equation.
Ph of buffer solution equation. It explains the concept. You can calculate the ph of a buffer solution or the concentration of the acid and base using the henderson hasselbalch equation. Example of calculating the ph of a buffer solution using the henderson hasselbalch equation including the ph of the buffer solution after adding some naoh. Suppose you wanted a buffer with a ph.
Where you have done calculations using this equation. A buffer solution more precisely ph buffer or hydrogen ion buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or vice versa. How do buffer solutions work. You can calculate the ph of buffer solution in two ways.
Derivation of the henderson hasselbalch equation. Solutions able to retain a constant ph regardless of small amounts of acids or bases. In chemistry the hendersonhasselbalch equation describes the derivation of ph as a measure of acidity using pk a the negative log of the acid dissociation. Heres a look at the henderson.
First you can use the acid dissociation constant expression and second you can use the henderson.
