CO3-- is negative two
In other words it has two more electrons than protons
K + is plus one.
in other words it is missing an electron
To make it all come out a neutral solid salt you need two K ions for every one carbonate ion
so
K2CO3
GOOGLE potassium Carbonate

When ionic salt is dissolved in water the ions CO3 and K+ are formed?
KCO3
K2CO3
K(CO3)2
K3CO2
I think its the second one but I don't know where the 2 comes from?
