State Symbols ?

This question may sound silly .. but how do you know when writing an equation what the state symbol would be. I usually would know if it is a sold, liquid or gas but how do you know if it is an aquaneous ? 

Thanks

An aqueous solution is a compound mixed with water, a liquid is the molten form of that compound.

Ex. NaCl (aq) - a solution of salt mixed with water.
NaCl (l) - the solution in molten form, not mixed with water.

Hope I helped!

Hi Secret!!!!

As far as I can recall, there's no basic criteria upon which to tell what the state symbol of a substance is (just hav 2 know it) but in A'Levels I think they do but I'm not actually 100% certain; apperently the substance has HCl in its formular but it could be wrong.

Hope this helped.

if the question says desolved in water then its aq if it says molten it is l if it says solid it is S

some common compounds and there state symbols

NaCl          normally aq but some times s  ocasionly l

CO2          g

O2           g

N2            g

CaCO3      s

HCl          aq or g

any ionisation energy questions then it MUST be g
