Title: Methods to verify molarity of a prepared/diluted solution?
Post by: Thought Hammer on November 14, 2010, 11:16:30 PM
I have already found out that I can titrate and use stoichiometry to verify that the molarity of my prepared(diluted) solution of HCl is close to the target value of .3500M.

However, I am befuddled on how to approach another method (my teacher says that density should be used but I am doubtful on that statement).

If someone has any ideas on any methods, please help. Thanks!

You can measure density and check in density tables (not too accurate), you can use refractometry, you can use pH meter. Plenty of possibilities, but a lot depends on what you have at hand.

Do you know the molarity of your stock/initial solution? In that case:

C1V1 = C2V2
