We are being asked to determine the pH of of a 2.9 M solution of HClO_{4}.

The **pH **of a compound determine its acidity and basicity.

▪ pH stands for the negative logarithmic function of hydronium ion concentration**▪** can be calculated using the following equation

$\overline{){\mathbf{pH}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{-}}{\mathbf{log}}\mathbf{\left[}{\mathbf{H}}^{\mathbf{+}}\mathbf{\right]}}$

Take note that: **[H ^{+}] = [H_{3}O^{+}]**

We will do the following steps to solve this problem:

**Step 1: Determine [H ^{+}]**

**Step 2: Calculate pH**

What is the pH of a 2.9 M solution of HClO_{4}?
