Question

What is the pH of a solution containing a 1.0 x 10−4 M solution of HCl?
Answer

1.00

4.00

1 x 104

1 x 10−4

Answer 1

pH = -log[H+]

Answer 2

Well, pH is the measure of H30+ or H+ ions in solution. Therefore, to find the pH you can use the formula pH = -log[H30+]

HCl is a strong acid and breaks up in a 1:1 ratio. For every Cl- ion, there is a H+ ion. Therefore, pH = -log[1.0 x 10^-4] = 4

Answer 3

um..
ok
I have another question like this, shall I try to find the answer and have you guys check it?

Answer 4

If you want, I'll post it separately so I can give credit
