The pk of a weak acid is 4.8 what should be the ratio of acid by salt of a buffer if ph is equal to 5.8 is required

The pk of a weak acid is 4.8 what should be the ratio of acid by salt

1.	The pk of a weak acid is 4.8 what should be the ratio of acid by salt of a buffer if ph is equal to 5.8 is required
Answer» For BUFFER solution pH=pKa+ $log$ [SALT]/[ACID] 5.8=4.8+log[salt]/[acid] 1=log[salt]/[acid] [salt]/[acid]=antilog1 [salt]/[acid]=10 [acid]/[salt]=0.1
