Which of these methods could be used to separate an insoluble solid from a soluble solid? melting the mixture and then using a filter to separate out the soluble solid melting the mixture, mixing it with water, and then using a magnet to separate out the insoluble solid mixing the mixture with water and then using chromatography to separate the two dissolved solids mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid

The answer is:

To separate an insoluble solid from a soluble solid:

Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.

That is when we mix the mixture with water , soluble solid got dissolved into it but insoluble solid won't, so it can be separated using filtering process so that it got collected into filter paper and rest soluble solid can be separated from water by evaporation as water evaporates leaving the soluble solid behind.

The method that could be used to separate an insoluble solid from a soluble solid is; Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.

A soluble substance can dissolve in water while an insoluble substance can not dissolve in water.

If a mixture containing a soluble and an insoluble substance is mixed with water, the soluble substance dissolve in water and the insoluble substance is filtered out and dried.

The filtrate can now be evaporated to dryness to recover the soluble substance.
