If a compound/atom/molecule is...
liquid, the state symbol is (l)
solid, the state symbol is (s)
gas, the state symbol is (g)
aqueous, the state symbol is (aq)
How to tell which state symbol to use... if your just given an equation, it may be hard to work out what is solid/liquid/gas/aqueous. Unfortunately there is no rule to learn that will give you the answer, but there are a few ways of working it out...
if a liquid (l) is heated, it will become a gas (g)
if a precipitate is formed, it will be a solid (s)
aqueous is anything dissolved in water, so if the compound contains an OH, it is most likely aqueous.
A blog covering and explaining the Edexcel IGCSE Chemistry specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)
