Answer to Question #146701 in General Chemistry for Clyff

Question

Calculate the hydronium concentration of a certain ionization reaction where the hydroxide concentration is determined to be 2.7 x 10-5 M. Identify if the solution is acidic, basic, or neutral.

Answer 1

pOH= -log(OH^-)

=-log(2.7×10^-5)

=4.569

pH= 14-pOH

pH= 14-4.569

=9.431

[H₃0⁺]= antilog(-pH)

=antilog(-9.431)

=3.707×10^-10 M

The solution is basic since pH is 9.431 and the concentration of hydroxide ions is more than that of hydronium.
