Pre$-$Laboratory Assignment

Reactions of metals with $1MHCl$ solution that produce $H_2$ gas can proceed with considerable intensity.

$(1)$ Briefly describe the hazards you need to be aware of when you work with $1MHCl$ solution.

$(2)$ Give two reasons why it would be unwise to almost completely fill a test tube with $1MHCl$ solution before adding a piece of metal. Briefly explain.

Briefly explain what is meant by the following terms as they pertain to this experiment.

$(1)$ comparative reactivities of metals

$(2)$ cation

$(3)$ oxidation

$(4)$ reduction
