Answer to Question #110884 in General Chemistry for Lea

Question

Each value below represents a different aqueous solution at 25 °C. Classify each solution as acidic, basic, neutral.

pH = 1.77
[OH^-] = 4.9 x 10^-5
pOH = 5.14
[H^+] = 1.0 x 10^-7
[H^+0 = 1.9 x 10^-5
pOH = 7.00
pH = 9.06
[H^+] = 5.0 x 10^-10
pOH = 13.53
[OH^-] = 4.6 x 10^-12

Answer 1

pH + pOH = 14

pH = 7 --> Neutral

pH > 7 --> Basic

pH < 7 --> Acidic

pOH = 7 --> Neutral

pOH > 7--> Acidic

pOH < 7 --> Basic

__________________________

[H⁺][OH^-] = 1x10^-14

[H+] = 1x10^-7 --> Neutral

[H+] > 1x10^-7 --> Acidic

[H+] < 1x10^-7 --> Basic

[OH-] = 1x10^-7 --> Neutral

[OH-] > 1x10^-7 ---> Basic

[OH-] < 1x10^-7 --> Acidic
