Hydrochloric acid 32%
Posted: 16 Mar 2007, 11:59
I may be missing something in my maths but can anyone help me with a problem regarding Hydrochloric Acid. Our concentrate come as 32% which is then described in manuals as 10 M.
I can't work out why, if the Molecular weight of HCl is 36.46 why 10M HCl should not be 36% and the 32% concentration about 8.8M.
Our senior chem has just started titrations and I'm being told my stock solution is out and am trying to work out why.
The chemistry teacher can't help me, his comment is "they may have just labelled it wrong!"
Thanks for any information,
Wendy
