Question

Write the balanced net ionic equation for the reaction that occurs in the following case: Cr2(SO4)3(aq)+(NH4)2CO3(aq)→ ?

Part A
Express your answer as a balanced net ionic equation. Identify all of the phases in your answer.

Part B
Identify the spectator ion or ions in this reaction.
Express your answer as an ion. If there is more than one answer, separate them by a comma.

Answer 1

The reaction is tentative.........

`Cr_2(SO_4)_3(aq) + 3(NH_4)_2CO_3(aq)rarr (NH_4)_2SO_4(aq)+Cr_2(CO_3)_3(s)darr`

Explanation:

`A.` `2Cr^(3+) + 3CO_3^(2-) rarr Cr_2(CO_3)_3(s)darr` is the net ionic equation.

`B.` The spectator ions are `"ammonium ion"`, `NH_4^+`, and `"sulfate ion"`, `SO_4^(2-)`, which do not take part in the reaction, and remain in aqueous solution.
