Problem

What is the pOH of a 0.040 M solution of HCIO3?

A) 12.6

B) 1.4

C) 12.9

D) 1.1

Solution

We’re being asked to calculate the pOH of 0.040 M HClO3

Step 1. Identify if HClO3 is a weak or strong acid/base

Step 2. Calculate for [H+] or [OH-]

Step 3. Calculate for pOH


Step 1. Let’s first determine what type of acid is HClO3

If your oxyacid has 2 or more oxygens than hydrogens then your oxyacid is a strong acid. 

Since we have 3 Os and 1 H in HClO3, HClOwill be categorized as a strong acid
