X and Y dissolve in water to form colourless solutions.
Table 1 shows the results of qualitative tests on these solutions.
Table 1
| Test | Result with solution X | Result with solution Y |
|---|---|---|
| Dilute hydrochloric acid added | Bubbles of gas produced which turn limewater cloudy | No visible change |
| Dilute nitric acid added, then silver nitrate solution | No visible change | A cream precipitate formed |
The anions in solutions of X and Y can be identified from the results of the tests shown in Table 1.
Draw one straight line from each solution to the correct anion present. Solution
