Question

What is the pH of a solution of 1.0 × 10^{-9} M NaOH
(include 1 digit after the decimal in your answer)?

Answer #1

For the next three problems, consider 1.0 L of a solution which
is 0.3 M NH4Cl and 0.2 M NH3 (Ka for NH4Cl = 5.6 x 10-10). Assume 2
significant figures in all of the given concentrations so that you
should calculate all of the following pH values to two decimal
places. 1. Calculate the pH of this solution. 2. Calculate the pH
after 0.10 mol of HCl has been added to the original solution.
Assume no volume change on...
