Answer to Question #307983 in General Chemistry for Jaja

Question

If 20 ml of 3 F NH3, and 5 g of (NH4) 2SO4 are added to 200 ml of water, what

is the hydroxide-ion concentration of the resulting solution? Calculate the pOH of

the solution.

Answer 1

To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

Hydroxide ion concentration =0.03M

POH value=2.43
