1.	20.0 L of 0.2 M weak acid (pK_(a)=5.0) is titrated against 0.2 M strong base. What is the pH at the equivalence point ?
Answer» `5.0` `7.0` `9.0` `11.0` Solution :At the equivalence POINT, solution will contain salt of weak ACID and strong base. Its solution on hydrolysis will be basic with `pH gt 7`. Value of 9 may be CHOSEN as the base is strong.
