Question

Determine the pH of a solution with a hydronium ion concentration of 1.6 x 10^-4 ?

Answer 1

PH is -ve log of H+ ions please write ur question more briefly what 1.6*10^-4

Answer 2

that is the whole questions

Answer 3

so h+ ion concentration is 1.6*10^-4 ph is 4.2

Answer 4

how did you get that?

Answer 5

i hope my ans is right

Answer 6

can you show your steps pleae so i can see how it is done

Answer 7

here it is how to do that do't look at 4.2
-log(1.6*10^-4)

Answer 8

hmm ok thank you

Answer 9

find that i don't have cal so 4.2 may be wrong

Answer 10

how did you get 4.2?

Answer 11

-log(1.6)+log(10^-4)=Ph

Answer 12

i think 4.2 is wrong u do cal

Answer 13

i got -4.2?

Answer 14

-log(1.6) = -.20

Answer 15

log(10^-4)= -4

Answer 16

log(ab)=loga +logb
log( 1.6 x 10^-4 )= log1.6 +log10^-4

PH=-log[H+]

log of 10^-4 is =-4 ok
log of 1.6 is =0.204 ok
now add them = -3.976 fine
but PH is - log multiply -3.976 by -1
ph=3.976

Answer 17

-.20+(-4)
=-4.2

Answer 18

oh ok ic
