Question

What is the pH difference of two samples if the concentration of [H+] ions is 1000-fold less in the second sample?

A. The pH of the first sample would be 3 pH units lower than the second sample.
B. The pH of the first sample would be 2 pH units higher than the second sample.
C. The pH of the first sample would be 3 pH units higher than the second sample.
D. The pH of the first sample would be 2 pH units lower than the second sample.

Answer 1

@rvc A or C?

Answer 2

Lower the pH value stronger is the acid

Answer 3

pH = - log_10[H+]

Answer 4

Since it is less the second sample is more acidic than the first one.

Answer 5

So it would be C

Answer 6

It was A

Answer 7

Oh
sorry :(
