Problem: What is the pH of 0.0157 M HBr?

FREE Expert Solution

We’re being asked to calculate the pH of  0.0157 M HBr

First, we need to identify whether the given acid is weak or strong. 

Weak acids are weak electrolytes that don’t completely ionize but instead reach a state of equilibrium. 

However, it’s easier to identify strong acids than familiarize yourself with all the weak acids (since the common strong acids have rules and are relatively fewer).
