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).
What is the pH of 0.0157 M HBr?
