This question is about the behavior of hydrogen chloride in different solvents.
A piece of zinc foil is added to hydrogen chloride in three separate experiments under different conditions:
| Experiment | Conditions | Observations |
|---|---|---|
| 1 | Hydrogen chloride gas | No visible change |
| 2 | Hydrogen chloride dissolved in water | The zinc gets smaller and bubbles are seen |
| 3 | Hydrogen chloride dissolved in methylbenzene | No visible change |
Write the formulae of two ions formed in the solution produced in Experiment 2.
Identify the gas formed in Experiment 2 and describe a chemical test for it.
Silver nitrate solution and dilute nitric acid are added to the solution produced in Experiment 2.
State the observation and name the substance responsible for this observation.
Explain why dilute nitric acid is added.
Explain why there is no reaction in Experiment 3.
