Question

Classify each aqueous solution as acidic, base, or neutral at 25 ° C.

1. [H⁺]=6.1x10^-4
2. [H⁺]=8.3x10^-11
3. [OH^-]=6.1x10^-9
4. pH=1.33
5. [OH^-]=7.6x10^-6
6. pH=12.06
7. pH=7.00
8. [H⁺]=1.0x10^-7

Answer 1

pH > 7 = basic

pH < 7 = acidic

pH = 7 = neutral

[H⁺] > 1x10^-7 = acidic

[H⁺] < 1x10^-7 = basic

[OH^- > 1x10^-7 = basic

[OH^-]< 1x10^-7 = acidic

[H⁺] = 1x10^-7 = [OH^-] = neutral

Use the above criteria to answer the question:

1. [H⁺]=6.1x10^-4 -- acidic
2. [H⁺]=8.3x10^-11 -- basic
3. [OH^-]=6.1x10^-9 -- acidic
4. pH=1.33 -- acidic

you should be able to do the others.
