What is the pOH of a 0.040 M solution of HCIO_{3}?

A) 12.6

B) 1.4

C) 12.9

D) 1.1

We’re being asked to calculate the pOH of 0.040 M HClO_{3}

**Step 1.** Identify if HClO_{3} 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 HClO _{3}**

• 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 HClO_{3}, HClO_{3 }will be categorized as a strong acid
