Question
A student is asked to standardize a solution of calcium hydroxide. He weighe out 0.920 g potansium hydrogen phthalate (0CO, treat this an a moneprotic adid).
It requires 19.0o mt of calcium hydroxide to reach the endpoint.
A. What is the molarity of the calcium hydroxide solution
IM
This calciunm hydroxide solution is then used to trate an unknown solution of hydrobromic acid.
B. If 24.8 ml of the calcium hydroxide solution is required to neeutralize 29.1 mt of hydrobromic acd, what is the molarity of the hydrobromic acid solution?
