During a class experiment, chlorine gas was bubbled into a solution of potassium iodide

During a class experiment, chlorine gas was bubbled into a solution of potassium iodide
a) State the observations made.
b) Give two uses of hydrochloric acid

Answers

a) The potassium iodide solution turned from colourless to dark brown.

b) Cl2(aq) + 2I-(aq) $\rightarrow$ I2(aq) + 2Cl-(aq)

Chlorine undergoes reduction while iodide ions undergo oxidation hence the reaction is redox.
