Answer to Question #192385 in General Chemistry for Chabiya

Question

Find the hydrogen and hydroxide ion in 0.03M of hydroxide solution

Answer 1

$[H^+]$ the hydrogen ion concentration in terms of molarity thus; Hydrogen ion =0.03

pH=$-log (0.03)=1.5$

pOH =14 $-$ 1.5=12.5

$[OH^-] =10^{-(12. 5) }=3.2×10 ^{-13}$
