Question

1. Indicate whether the solute solid is soluble or insoluble in each solvent liquid. SOLVENT nonpolar liquid, CoH14 polarl SOLUTE salt, NaCl sugar, CoH120 cholesterol, C27H460 2 lke dissolves like" nule, predict whether the following vitamins are soluble or insoluble in water. (a) vitamin A, C2oH300 (b) vitamin B-2, CI:HnN4Og (c) vitamin C, CHgO 3. Indicate whether the solute liquid is miscible or immiscible in each solvent liquid. SOLVENT polar liquid, H2O nonpolar liquid, C6H14 SOLUTE methanol, CH3OH pentane, CsH12 4. Based on the "like dissolves like" rule. predict whether the following solvents are miscible or immiscible with water. (a) gasoline, CsH18 (b) rubbing alcohol, C&H;,OH (c) chloroform, CHCl3

Explanation / Answer

Ans 1 :

There is a general rule for solubility that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Here NaCl and glucose are polar compounds so soluble in polar solvent water and insoluble in non polar solvent C6H14.

Cholesterol is non polar compound so insoluble in polar liquid water and soluble in non polar liquid C6H14.
