Given [OH-] 6.98 times 10^-2 what is the ph and [H+]

[H+]=1.43*10^-13

pH=12.84

Explanation:

Take the -log of the [OH-] to get the pOH:

pOH= -log(6.98*10^-2)=1.15

pH=14-pOH

pH=14-1.15

pH=12.843

[H+]=10^(-pH)

[H+]=10^(-12.843)

[H+]-1.43*10^-13

If I helped, a brainliest would be greatly appreciated!

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
