Answer:

#pH=pK_a+log_10{([A^-])/([HA])}#

Explanation:

See this older answer. You should review your understanding of the #"logarithmic function"#, because this is crucial in understanding how the equation works.

Biological systems are extensively buffered, and in a buffer, the #pH# of the solution remains tolerably close the to the #pK_a# of the original acid.
