Muriatic Acid vs. Hydrochloric Acid

Muriatic acid is also known as hydrochloric acid and the two terms are frequently used interchangeably. However, there is a slight difference between muriatic acid and hydrochloric acid. Muriatic acid is a diluted form of hydrochloric acid. It also includes some impurities (including traces of iron) which makes it a yellow color compared to hydrochloric acid’s colorless or very slight yellow tinge.

Muriatic acid comes in different concentrations so it’s best to check the label to make sure the concentration you are buying is appropriate for the task.
