Science WB p39 Q8 (Do in WB too)

Singapore relies on desalination to produce potable water. Which statement(s) about desalination process in SG is/are correct? (Refer to p6 of C4 notes)

I: Salt is removed from seawater

II: Distillation is involved.

III Evaporation is involved.

Which of the following key question(s) can determine the appropriate separation methods to separate a substance from a mixture?

During filtration, the insoluble solid that did not pass through the filter paper is known as (a)   .

During distillation, the pure liquid that is collected at the conical flask is known as (a)   .

During paper chromatography, how do we know that 2 dyes are different on the chromatogram?

(a)  

During filtration, the insoluble solids are unable to pass through the filter paper because the insoluble solids were too _____________________________________________________.

Evaporation to dryness used ______________________________ to remove liquid from the solution.

How do we tell the difference between a suspension and a solution in your own words?
