What is the pH of a 2.5 mol HCL / liter aqueous solution?
Hello and thank you for posting your question to brainmass!
pH is the negative log of the hydrogen ions concentration in the solution:
When the concentration is given in molars (mols per litre).
We examine the dissolution equation of HCl:
HCl --> (H+) + (Cl-)
and see that for every mole ...
The solution decribes the straightforward method of finding the pH of HCl solution.
