Text p k_ a pk a of acetic acid
WebThe acetic acid has a pK a of about 4.8. It may therefore be used for making buffer solutions with pH values lying roughly between the range 3.8 to 5.8. Relation between pK a and pK b … WebAs a simple example for a weak acid with K a = 10-5, log K a is the exponent which is -5, so that pK a = 5. And for acetic acid with K a = 1.8 x 10-5, pK a is close to 5. A higher K a …
