The mixture can be separated into three separate components by using a centrifuge and a separating funnel.
A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.
-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.
- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.
- The remaining liquid on the separating funnel can be collected in a different flask.
-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.
- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube
Answer:
1.015g
Explanation:
From the question,
Mass of Al used = 0.660g
The percentage yield = 63.5%
Mass of Alum used = y
To find the mass of Alum used, do the following:
%yield = Mass of Al /Mass and Alum
65% = 0.660/y
65/100 = 0.660/y
Cross multiply
65 x y = 0.660x100
Divide both side by 65
y = (0.660x100) / 65
y = 1.015g
The mass of alum obtained is 1.015g
