The chemical formulae of some chemical compounds are written in the first column of the table below. Each compound is soluble in water.
Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution.
Note: "major" chemical species are those present in concentrations greater than 10^-6 mol/L

C3H6(OH)2 : ?
FeI3 : ?
C3H8O : ?

I know that the first species in each one is H2O, water, but we never actually learned this in class as far as I know so I don't really know how to solve it. Thanks to anyone who can help with this!
