Question

What is the pH of a solution with a concentration of 4.7 × 10-4 molar H3O+? Show, or explain, the work used to solve this problem.

Technically a math question ;D

Answer 1

pH = -log[H3O +]
pH = -log (4.7 x 10^-4) ≈ 3.33

Answer 2

Thank you times a million!

Answer 3

the result is 6

Answer 4

Kumar-san, may I know how you managed to get 6? Thank you...

Answer 5

i too think i should be near about 2-3

Answer 6

pH = -log [H+]
1. pH = - log(1.8 x 10^-4)= 3.74

Answer 7

haha now I have three results! I'm sticking to @kira_yamato

Answer 8

That is wrong.

Answer 9

It's
pH = -log [H+]
1. pH = - log(1.8 x 10^-4)= 3.74

Answer 10

it should be -log(4.7x10^-4) and not of 1.8x10^-4

Answer 11

how?

Answer 12

in question it is 4.7x10^-4

Answer 13

This question belongs in Chem. Thanks!

Answer 14

True

Answer 15

yaaaa.....wrong place
