Question

Pick an appropriate solvent(s) from table to dissolve each of the following substances. Common Polar Solvents Common Nonpolar Solvents water (H2O) hexane (C6H12) acetone (CH3COCH3) diethyl ether (CH3CH2OCH2CH3) methyl alcohol (CH3OH) toluene (C7H8) Part A glucose (polar)

Part B salt (ionic) Part C vegetable oil (nonpolar) Part D sodium nitrate (ionic)

Answer 1

The appropriate solvent choices for dissolving glucose would be water, for salt water again due to its ionic properties, for vegetable oil a nonpolar solvent like hexane or toluene, and for sodium nitrate, a polar solvent like water.

Step-by-step explanation:

Choosing the Right Solvent for Substance Dissolution

To pick an appropriate solvent to dissolve each substance, we must consider the polarity of both the solvent and the solute. The principle that 'like dissolves like' is essential in determining the solubility of a substance.

Part A: Glucose (polar)

Glucose is a polar substance, so water (H2O) would be the appropriate solvent to dissolve it.

Part B: Salt (ionic)

Salt, being ionic, dissolves well in polar solvents like water due to the solvent's ability to separate the ionic bonds.

Part C: Vegetable Oil (nonpolar)

Vegetable oil is nonpolar, thus it will dissolve in a nonpolar solvent such as hexane (C6H12) or toluene (C7H8).

Part D: Sodium Nitrate (ionic)

Sodium nitrate, an ionic compound, will be more soluble in a polar solvent like water.
