weak acid 100.0 mL 0.09381 M NaOH 27.63 mL pH 10.99 16.47 mL
약산 100.0 mL를 0.09381 M NaOH로 적정할 때,
당량점에 도달하는데 27.63 mL가 소모되었으며
당량점에서의 pH는 10.99였다.
NaOH 용액 16.47 mL만을 첨가시켰을 때,
pH는 얼마인지 계산하시오.
When 100.0 mL of a weak acid were titrated with 0.09381 M NaOH, 27.63 mL were required to reach the equivalence point. The pH at the equivalence point was 10.99.
What was the pH when only 16.47 mL of NaOH had been added?
