Please correct my work
« on: October 01, 2008, 05:31:49 PM »
Write the reaction for the dissolution of ammonium chloride in water?

Na2CO3 (s) → 2Na+ (aq) + CO32- (aq) (insoluble)?

Should CO32- be written as a (s) insoluable or an (aq) for soluble?

Thanks,

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.  :o  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) :rarrow: 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.
