Question

Solutions of aluminum nitrate and sodium sulfate react to form sodium nitrate and aluminum sulfate. Classify this reaction.

Answer 1

Answer:

Double replacement.

Explanation:

In the given reaction, there is not synthesis of compound.

The decomposition reactions are those in which a compound dissociates into simpler molecules or ions.

So the given reaction is not decomposition even.

In single replacement reactions, there is replacement of one group from a compound to other compound or element or ion.

Here two groups are being replaced (sulfate and nitrate) so the given reaction will be classified as double replacement.

Answer 2

2 Al(NO₃)₃ + 3 Na₂SO₄ = Al₂(SO₄)₃ + 6 NaNO₃

Aluminium Nitrate + Salt Cake = Aluminium Sulfate + Sodium Nitrate

Answer D  ( double replacement )

hope this helps!
