Potassium Carbonate Dihydrate
Questions about chemical formulas?
Well, first write the formula of aluminum carbonate.
K ^ + 1
CO (3) ^ 2 (3 is the index because there are 3 oxygen)
K (2) CO (3)
Dehydrate is only 2 water 2H (2) O.
Everything is K (2) CO (3) 2H2O
Brackets indicate that these values must be indexed. Slide is one of them.
Help you for example.
