help me with this...Calculate the value of OH from the given

Note: The ion product of water = 1.0 x 10-14

Part 1 of 2

H3O+

in each solution and label the solution as acidic, basic, or neutral.

M

Be sure your answer has the correct number of significant figures.

[H30+]=10-3 M

[OH-]=

This solution is (Choose one)

Part 2 of 2

M

(Choose one)

Be sure your answer has the correct number of significant figures.

[H30+]= 7.7 x 10-11 M

OH=

This solution is

[H30+]=10-3 M

[OH-]=1.0 x 10-14 / 10-3 = 1.0 x 10-11 M

This solution is basic.

[H30+]= 7.7 x 10-11 M

OH=1.0 x 10-14 / 7.7 x 10-11 = 1.3 x 10-5 M

This solution is neutral.
