HELP! How to find a method to determine the molar mass of a soluble acid X??
I am provided with the following apparatus:
Monobasic Acid (KHC6H4O6) - Potassium Phthalate (Mr of about 202.4)
Aqueous Sodium Hydroxide (0.1M)
Indicator
Acid X monobasic (whose molar mass I have to find!)
Normal laboratory equipment
The question is to design a method to find the molar mass of the soluble acid x
ACID + OH -- H20 + ACIDrest (I got this from my friend but I have no clue what this has to do with the stuff I have said above)
What I came up with after a lot of thinking was a simple titration
I could titrate with NaOH. But then I am not sure whether to use some amount of acid x or the mixture of acid x and potassium phthalate or just potassium phthalate. I am really confused here!
Please Please HELP!
