Write the reaction for the dissolution of ammonium chloride in water?

Na₂CO₃ (s) → 2Na⁺ _(aq) + CO₃^2- _{(aq) (insoluble)?}

Should CO₃^2- be written as a (s) insoluable or an (aq) for soluble?

Thanks,

qbkr21

Na₂CO₃ is not ammonium chloride.

Ions are always (aq).

Note that (aq) should be not a subscript, it should be placed exactly on the same level as normal text. If your teacher/book states otherwise, they are wrong. This is IUPAC defined thing.

Sorry I typed the wrong reaction.

The one posted is the reaction for the dissolution of sodium carbonate in water.

Write the reaction for the dissolution of ammonium chloride in water: Is this correct?

NH₄Cl(aq)

NH4⁺(aq)+ Cl^-(aq)

Again I would love to know if this is correct and sorry for the earlier confusion.

Best,

NH₄Cl(s) - you start with solid.
