When using distillation to separate 3 different liquids with different boiling points, which liquid will be removed first?

Fractionating columns help condense prematurely boiling liquids. Which is NOT a reason for this:

TRUE or FALSE: At 66 °C, without a fractionating column, you might get some ethanol contamination in your condensed and collected methanol.

If you had salt water and you were trying to extract the salt from it, you would use

When we separated a mixture of salt and sand in a lab, which technique did we NOT use?

If you had salt water and you were trying to extract and purify the water from it, you would use

When a solute in solution could be damaged by thermal decomposition, which technique would be better to use?

What term describes how much of a solute can dissolve in a solvent?

The process for making rock candy and borax crystal ornaments was the same except a different ______ was used.

The different dyes used to make a marker were separated with chromatography. Which color had the GREATEST Rf value?

The different dyes used to make a marker were separated with chromatography. Which color had the SMALLEST Rf value?

Which dye is probably the LEAST soluble in the solvent used?

With a sharpie marker, why did the dot not move on the chromatography paper with a water solvent, but it did move with an alcohol solvent?
