Question

Emma is doing a laboratory experiment to separate components of crude oil. She decides to use a technique that will separate the components based on their boiling points. Which technique uses this principle?

a.filtration
b.distillation
c.centrifugation
d.chromatography
e.titration

Answer 1

Distillation works by isolating compounds with different boiling points. Filtration can only separate heterogeneous mixtures. Centrifugation can often separate colloids and suspensions. Chromatography uses capillary action to separate differently-colored compounds. Titration tells you the concentration of an acid or base. Hope this helps!
