Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100. g of a coarse grey powder with a faint unpleasant smell, 15, g of the powder is put into a funnel lined with a sheet of thick paper. Distilled water is poured slowly over the powder. All of the powder disappears, and the water under the funnel turns a deep purple. . Sample B is 100. mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77 g/mL. The liquid is then cooled in the refrigerator At 10.0 °C crystals begin to appear. The temperature of the liquid continues to decrease as more crystals form, until at 6.2 °C the liquid is entirely solid. Is sample A made from a pure substance or a mixture?

Transcribed Image Text:Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure
substance or a mixture, if you can.
. Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. g of the powder is put into a funnel lined with a sheet of thick paper.
Distilled water is poured slowly over the powder. All of the powder disappears, and the water under the funnel turns a deep purple.
.
Sample B is 100. mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77 g/mL. The liquid is then cooled in the refrigerator
At 10.0 °C crystals begin to appear. The temperature of the liquid continues to decrease as more crystals form, until at 6.2 °C the liquid is entirely solid.
Is sample A made from a pure substance or a mixture?
If the description of the substance and the outcome of
the experiment isn't enough to decide, choose "can't
decide."
