In general, when a pure substance or mixture goes from liquid to solid, the molecules in it get closer resulting in a higher density.

If this is so why does ice float in water?

this procedure - (frozen water), contains oxygen as an element. When frozen, the other elements combine, thus allowing the oxygen element to expand, making the entire frozen object to become light enough to float.
