Question

A solution with a hydroxide ion concentration of 4.15 × 10-6 m is __________ and has a hydrogen ion concentration of __________. acidic, 2.41 × 10-8 m basic, 2.41 × 10-9 m basic, 2.41 × 10-8 m acidic, 2.41 × 10-9 m

Answer 1

A solution with hydroxide ion concentration of 4.15 x10^-6 m is basic and has a hydrogen ion concentration of 2.41 x10^-9 M

we well know thaat (H^+) (OH^-) = 1 x10^-14

by making H^+ concentration the subject of the formula

H^+ = 1 x10^-14/OH^-
H^+= 1 x10^-14/4.15 x10^-6 = 2.41 x10^-9 M

the solution is basic since OH^- ion is for basic solution
