Question

What is molarity of acetic acid in 0.1M solution..??

Answer 1

As Acetic Acid is a weak acid, it doesn’t completely dissociate in an aquous solution. It dissociates partially. And the amount of dissociated H+ ions can be counted using Ostwald’s Dilution Law.

The Ka value for acetic acid, CH3COOH(aq), is 1.8x10^-5

so, using Ostwald’s Dilution Law and pH Scale Definition,

we can write=> pH=−log(sqrt(Ka∗C))pH=−log(sqrt(Ka∗C))

where, C=0.1 M

so, pH=2.87 (by calculating)
