How do you know if a substance is pure?
Impure substances tend to have a slightly lower melting point than the pure substance, and a broader melting temperature range. Pure substances can be identified by comparing the melting point found in the experiment with published reference data of what the melting point should be.
Is ice a pure substance?
Both ice and liquid water are the same substance. H2O Though ice water is a mixture of both solid and liquid it is a pure substance, based on the molecular structure of its components .
Why is tea a mixture?
