Problem 12.25 6th edition

Postby Jane Burgan 1C » Thu Dec 06, 2018 11:40 pm

Calculate the initial molarity of Ba(OH)2 and the molarities of Ba2 , OH , and H3O in an aqueous solution that contains 0.43 g of Ba(OH)2 in 0.100 L of solution.
How do you do this problem?

First, you must find the molarity of Ba(OH)2. Review fundamentals from the very beginning of the quarter.
For every one mole of Ba(OH)2 you have, you also have 2 moles of OH. Calculate [OH-].
Use Kw equation where [H+][OH-]=Kw to solve for H+.
