You are given a 100ml bottle of sodium hydroxide..

You are given a 100ml bottle of sodium hydroxide. It contains 0.01 moles of hydroxide ions.

What is the pH of the solution?

use the Molarity= moles/volume equation

convert 100mL to Liters= 0.1 Liters

plug in to solve for Molarity: 0.01 moles/0.1= 0.1 M

now use a calculator and solve using : pH= -Log( 0.1 M)= 1 pH


The pH of the solution is 1.
