Equal masses of steel wool are placed in four beakers. Equal amounts of hydrochloric acid (HCL) are added to three beakers in the following concentrations: 0.5 M, 1.0 M and 3.0 M. Water is added to the fourth beaker. Hydrochloric acid reacts with the metal in steel wool. Which observation is most likely? The mixtures react in the same amount of time.

The steel wool in the 3.0 M HCL reacts fastest.

The steel wool in the 0.5 M HCL reacts fastest.

The control reacts in the shortest amount of time.
