Question

Calculate the pH of concentrated hydrochloric acid if this solution is 24.8 % HCl by weight and has a density of 1.16 g/mL.

a. ) -0.77
b. ) -0.83
c. ) -0.90
d. ) -0.98
e. ) -1.01

i got c) by converting density into concentration (mol/L) and then, multiplying by 0.248. next, i took the negative log of the concentration to find pH.

is that how u would solve the problem?

Answer 1

Yes, your procedure as well as the answer is correct.
