In an ideal scenario, do you believe there were any impurities in the products (aside from water andacetone) of the vacuum filtration method? Do you believe there were any impurities in the products of theevaporative collection method?If yes, be sure to state which impurities are in the products and use experimental evidence to supportyour answer, or use experimental evidence to support why you believe there are no impurities in theproducts.Hint: It may be helpful to refer to section 1.3 in your textbook.

Which is a correct laboratory technique? * The minimum number of centrifuge tubes in a centrifuge machine during its operation is one. An open flame is the heat source for heating or evaporating flammable liquids. Never place reagents directly onto the weighing pan of a balance, always use weighing paper, a beaker, or some other container. Water or glycerol should not be applied to the glass tubing and to the hole in the rubber stopper before inserting the glass tubing.
