Calculate the pH of a solution with [H + ] = 1.45 x 10 -10 M. b) Is the solution acidic, basic,
or neutral?

Edit: I would really like some help with this, as I do not really understand how to put it into my calculator or how to calculate this. Thanks!
pH = -log(H^+)
I don't know what kind of calculator you have and I'm not sure that would help me even if I did but look on your calculator for a button that is log. Press the - key, press the log button, enter the hydrogen ion concentration on the keypad, then hit enter/calculate/whatever you do to get the answer. Try it first to see that you have the hang of it.
For example, when H+ = 0.01 the pH is 2
When H+ = 0.001 the pH is 3
etc.
When (H^+) = 1.45E-9 M, the pH is 8.84 and that's the number you should get. For the solution remember this:
If pH is <7.0 the solution is acid.
If pH = 7.0 the solution is neutral.
If pH is >7.0 the solution is basic.
