Question

A student wants to create a buffer our of a weak acid. The buffer should be a higher pH than the value obtained by: -log Ka. Which of the following statement(s) is true. (circle the correct one or ones) i. [base] > [acid] ii. [base] > [acid] iii. [base] = [acid] briefly explain your answer. A student wants to create a buffer our of a weak acid.

Explanation / Answer

buffer formula :

pH = pKa + log [base / acid]

pKa = -log Ka

we needed to get more than pKa . that mena pKa + something value

for this base > acid .

pH = pKa + something

answer : i. [base] > [acid]
