kira_yamato · Answer

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

Thank you times a million!

anonymous · Answer

the result is 6

kira_yamato · Answer

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

kunal · Answer

i too think i should be near about 2-3

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

That is wrong.

anonymous · Answer

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

kunal · Answer

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

anonymous · Answer

how?

kunal · Answer

in question it is 4.7x10^-4
