Using the chemical equation Cl2 + H2O ⇌ HCl + HOCl, predict the effect on the odour of chlorine water when acid is added to it.

making an educated guess here so i can't be totally sure. reversible reaction here, you've got a diatomic chlorine molecule added to water to give hydrochloric acid and chlorine water. since its reversible you can go backwards: chlorine water + an acid ( in this case HCl ) gives water and diatomic chlorine. water is odourless so I'm guessing they're asking what chlorine would smell like which is pungent/strong bleach smell. if someone sees this and knows it's wrong please please correct me. hope this helps.

You're correct, adding more HCl will cause the equilibrium to shift to the LHS. sleepsonggarden9 what do you think happens next?
