A
One which the pH remains constant when small amounts of acid or base or water added
1
Q
Explain the graphs with diff strengths of acid and alkali
A
Strong acid and alkali is pH 7
Strong acid weak alkali below 7
Weak acid strong alkali above 7
Weak acid and alkali pH 7 straighter line
2
Q

A
pH = pKa - log [acid/salt]
