OH^-=

1 answer

Part 1:

[H3O+] = 10^-5 M
To determine if the solution is acidic, basic, or neutral, we need to compare the concentration of H3O+ ions to the ion product of water (1.0 x 10^-14).

Since [H3O+] is less than the ion product of water, the solution is neutral.

Part 2:

[H3O+] = 3.8 x 10^-7 M
To calculate the value of OH-, we can use the equation for the ion product of water:

[H3O+][OH-] = 1.0 x 10^-14

We can rearrange the equation to solve for [OH-]:

[OH-] = (1.0 x 10^-14) / [H3O+]
[OH-] = (1.0 x 10^-14) / (3.8 x 10^-7)
[OH-] = 2.63 x 10^-8 M

So the value of OH- is 2.63 x 10^-8 M.
