FREE Expert Solution

We’re being asked to determine the pH of a 0.0150 M aqueous solution of rubidium hydroxide (RbOH).


Let’s first determine what type of base is RbOH:

Any Group 1A metal when combined with OH-, H-, O2- or NH2- makes a strong base

Rb (Group 1A metal) is paired with OH-

RbOHstrong base


We're going to calculate the pH of the solution using the following steps:

Step 1: Determine the OH- concentration in the solution.
Step 2: Calculate for pOH.
Step 3: Calculate for pH.
