Question

Part 1: Name the type of chemical reaction that occurs when magnesium chloride solution (MgCl2) reacts with sodium carbonate solution (Na2CO3). Part 2: Explain why aluminum (Al) would react with copper chloride (CuCl2) but not with magnesium chloride (MgCl2).

Answer 1

Answer: Part 1: The reaction is considered as replacement reaction and produce preciptate.

Part 2: Due to Mg is more active than Al.

Explanation:

Part 1: the reaction is replacement reaction due to the ions is replaced with each other as this equation shows:

MgCl2 + Na2CO3 → MgCO3 + 2NaCl

and MgCO3 is a white precipitate.

Part 2:

Al reacts with CuCl2 because Al is more active than Cu.

Al can not react with MgCl2 because Mg is more active than Al.
