Sodium hydroxide is used extensively in acid-base titrations because it is a strong, inexpensive base. A sodium hydroxide solution was standardized by titrating 42.18 mL of 0.1753 M...

Question

standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 1.08 mL, and the final reading was 31.51 mL. What was the molarity of the base solution?

I got 0.2212 M but it says that is the wrong answer.

Answer 1

Hi Dawson H.,

Your calculation should be 42.18*0.1753/(31.51-1.08) = 0.2430 M as rounded. I suppose you didn't correct for the initial titration buret level?
