Question

The pH of a liquid is a measure of how acidic or basic it is. The concentration of hydrogen ions in a liquid is labeled [H+]. Use the formula pH=-log[H+] to find the pH level, to the nearest tenth, of a liquid with [H+] about 6.2x10^-14.

answer options are:
A) -14.8
B) 14.8
C) 13.2
D) -13.2

Answer 1

pH = -log10[6.2x10^-14] = 13.2

Answer 2

Did you recheck the previous question btw? I think you closed it a bit early o.O

Answer 3

yeah... was i wrong?

Answer 4

Answer 6

This is what I came up with.

(5.4*10^-14)
= -log 5.4 + 14
= 14 - .732 = 13.268
