Question

which of the following [H+] values descirbes a nuetral solution?
10^-12M
10^-7M
10^-14M
10^-1M

Answer 1

For this, you need to understand what pH is -log[H+]

neutral solution of water means that the concentration of H+ equals the concentration of oH-

Usually at 25 degrees celsius

\[Kw = [H^+][OH^-] = 1*10^-14 \]

As i said if the solution is neutral [H] = [OH-] and for this to be the case their product has to equal so what do you think it might be?

Answer 2

i honestly have no idea

Answer 3

well for the concentrations to be equal they both have to be {10^-7]

because

[10^-7][10^-7] = 10^-14

Answer 4

oh ok.
