Answer to Question #286304 in General Chemistry for Hakak

Question

the ph of a solution 11.5 calculate the hydrogen ion concentration of solution?

Answer 1

1. pH= -lg[H⁺]

[H⁺]=10^^-pH=10^-11.5 = 3.16 × 10^-12

2.pOH=14 - pH=14-11.5= 2.5

pOH=-lg[OH^-];

[OH^-]=10^-2.5 = 3.16×10^-3

Answer: 1. 3.16 × 10^-12 M

2.3.16×10^-3 M
