This question is about sulfuric acid.
Dilute sulfuric acid, H2SO4(aq)\text{H}_2\text{SO}_4(\text{aq})H2SO4(aq), reacts with many metals.
A student observes the reaction of dilute sulfuric acid with four metals, A, B, C, and D. She uses the same amount of metal in each case.
The table shows her observations:
| Metal | Observations |
|---|---|
| A | few bubbles produced slowly |
| B | very many bubbles produced extremely quickly |
| C | no bubbles or visible change |
| D | many bubbles produced quickly |
Use the information in the table to place the four metals in order of reactivity. Place the most reactive first.
Give the names of the two products formed when zinc reacts with dilute sulfuric acid.
Describe a test to show that dilute sulfuric acid contains sulfate ions.
