Answer to Question #173183 in Organic Chemistry for Diane

Question

Determine (OH), ph and pOH of a solution [H]+ with 2.5 X 10 -8 M

Answer 1

H⁺ ion Concentration = 2.5×10^-8 + 10 ^-7

So , H⁺ ion Concentration = 1.25 × 10^-7

So, P^H = -log 1.25 × 10^-7 = 6.9( approx ).. ans.

P^OH = 14 - 6.9 = 7.1 ( approx ) .. ans.

Concentration of OH^- = 10^-7.1 ( approx ) ans.
