Answer to Question #176497 in General Chemistry for Yana Prakhina

Question

Calculate the [H3O+] and the [OH-] for each of the following:

0.0454 M H3PO4

1.00 x 10-8 M KOH

7.78 x 10-3 M H2SO4

0.0213 M Al(OH)3

Answer 1

$[H_3^{+}O] =3.80×10^{-11}M$

$[OH^{-}] =2.9×10^{-11}M$

$[H^{+} _3O]=0.048M$

$[OH^{-}] =0.037M$
