What is the pH of a solution in which [OH-1]= 0.010 M?

Question

2.00

10.00

12.00

13.00

Answer 1

omg this is soooo easy...

you have to -log it to get the pOH, you get 2

then you subtract it from 14, because pH + pOH=14

the answer is 12.00

and just so you know if you're going from lets say pOH to the [OH], you would antilog the number 2 to get 0.010 M, same with pH, if you have pH and need the [H3O], you antilog it to get your answer. but lets say they're asking for the [H3O], and they give you the [OH], you have to get the pOH, then the pH, then antilog that to get the [H3O]... did they teach you the box trick how to remember this??? and did they teach you H3O is the same as H+?

Answer 2

what does pH mean

Answer 3

Ever heard of...

search it out and stop trying to get others to do your homework. Thats not what the internet is for!

Answer 4

i think 12.00 cause PH= -1* logarithm*[H+]

As [OH-]=0.01so [H+]=0.000000000001

As as result PH = -1*0.000000000001*log.=12.00=ANSWER

always remember [OH-]*[H+]=0.00000000000001 so u can calculate both of them when u have only one of them.

Answer 5

pH = -log[H+]

[H+] x [OH-] = 10^-14

[OH-] = 10.0^-2, so [H+] = 10.0^-12

-log 10^-12 = 12, so your pH is 12.00

Answer 6

someone is trying to cheat on a homework assignment lol idk

Answer 7

10

Answer 8

one half of a third multiplied by 7.5 divided by 12.
