pH of .03M nitric acid at 50 celcius. also pOH

Does the temp make this problem change from just doing -log of.03 thanks
I know the Kw changes but still the OH- and H+ from water is very small.

Unless you know how pKa for nitric acid depends on temperature, temperature doesn't matter when calculating pH. But it will be important for pOH.

I don't know how it affects. I can't find an equation or descrption.

pH nitric acid -log .3 =  .52
Then is it Kw is 5.47x10^-10 so so pkw 9.26

then pOH 8.74?

I was talking to a friend and he was saying something about subtracting from a new nuetral?

Don't worry about that then.

pH nitric acid -log .3 =  .52

0.3 or 0.03?

Then is it Kw is 5.47x10^-10 so so pkw 9.26

No, please compare http://www.chembuddy.com/?left=pH-calculation&right=water-ion-product

then pOH 8.74?

Correct approach, but incorrect numbers.

ok thanks
