Answer to Question #56449 in General Chemistry for kelly

Question

Determine whether the following hydroxide ion concentrations ([OH−]) correspond to acidic, basic, or neutral solutions by estimating their corresponding hydronium ion concentrations ([H3O+] using the ion product constant of water (Kw).
**It may help to keep the following equation in mind as you work
Kw = [H3O+][OH−] = [1×10−7 M][1×10−7 M] = 1×10−14 M
Question is: Which are acidic, neutral or basic?
[OH-]=10x10^-12M
[OH-]=7x10^-9M
[OH-]=7x10^-4M
[OH-]=8X10^-10M
[OH-]=1X10^-5M
[OH-]=4X10^-13M
[OH-]=1X10^-7M
[OH-]=2X10^-2M
