EXPERMENT 19 DATE SECTION 1. Indicate whether the solute solid is soluble or insoluble in each solivent liuid SOLVENT SOLUTE 2. Based on the "like dissolves like" rule, predict whether the following vitamins are soluble or insoluble in water (a) vitamin A. CzoH3o0 (b) vitamin B-2, C1H20N 0s (c) vitamin C. C&HsO;% 3. Indicate whether the solute liquid is miscible or immiscible in each solvent liquid. SOLVENT polar liquid, H20 CoHi4 SOLUTE methanol, CHiOH pentane, CsHi2 4. Based on the "like dissolves like” rule, predict whether the following solvents are miscible or immiscible with water.

Explanation / Answer

1)

Salt NaCl is ionic solid it is composed of Na+ and Cl- ion and are held together by stron electro static force of attraction. So it is soluble in water

Sugar is a organic compound and it is soluble in non polar liquid effectively compare polar liquid water.

Cholestrol is completely organic compound and it is highly soluble in non polar solvent.

2)

Vitamin A is insoluble in polar but soluble in non polar molecule due non polarity of the molecule

Vitamin B is soluble in polar as well as non polar solvents due to presence of polar parts and non polar parts in the molecule

Vitamin C is is soluble in polar as well as non polar solvents due to presence of polar parts and non polar parts in the molecule

3)

Methanol is misicible in polar liquid H2O due to presence of polar part OH group in CH3OH and miscible in C6H14 due to the presence of non polar part CH3 in CH3OH

Petane in only misicible in C6H14 due to presen only non polar part in pentane.

4)

Gasoline dissoleves only in non polar solvent

Rubbing alcohol dissolves in majorly in non polar solvent and very little in polar solvent due to the presence of polar OH part in compound.

Chloro form is soluble in non polar solvent
