What is the pH value of concentrated hydrochloric acid?
Answer:
Usually concentrated HCl is 37% by mass and has density = 1.18 g /m L
d = 1180 g/L
1180 g/L x 37 / 100 = 436.6 g/L
Molar mass HCl = 36.46 g/mol
436.6 g/L / 36.46 g/mol = 12 mol/ L = 12 M
pH = - log 12 = - 1.08
Note : pH may be < 0
that depends on the exact concentration
otherwise
it is 1
