Is iced water a pure substance? Why?

Iced water can be considered a pure substance if it is composed solely of H₂O molecules with no impurities. Here are a few points to consider:

Composition: Pure iced water is just water (H₂O) in solid (ice) and liquid states. Both states have the same chemical composition, which makes it a pure substance.

Phases: The presence of both ice and liquid water does not alter the fact that the substance is pure. Phase changes do not affect the purity of a substance.

Impurities: If the iced water contains dissolved minerals, salts, or other impurities, then it would no longer be considered a pure substance.

In summary, iced water can be a pure substance if it consists entirely of water molecules without any other substances mixed in.
