2.116 Classify each of the following as a compound, a homoge-
neous mixture, or a heterogeneous mixture: (a) orange juice;
(b) vegetable soup; (c) cement; (d) calcium sulfate; (e) tea.
Problems in Context
2.117 Which separation method is operating in each of the follow-
ing procedures?
(a) Pouring a mixture of cooked pasta and boiling water into a
colander
(b) Removing colored impurities from raw sugar to make refined
sugar
2.118 A quality-control laboratory analyzes a product mixture using
gas-liquid chromatography. The separation of components is more
than adequate, but the process takes too long. Suggest two ways, other
than changing the stationary phase, to shorten the analysis time.
