We're being asked to calculate the pH of a 0.542 M solution of HCl.
Recall that HCl is one of the strong binary acids.
Recall that strong acids completely dissociate in water and that acids donate H+ to the base (water in this case). The dissociation of HCl is as follows:
HCl(aq) + H2O(l) → H3O+(aq) + Cl–(aq)
What is the pH of a 0.542 M solution of HCl? enter your answer with two decimal places.
