Homework Answers
Q3) "Like dissolves like" rule is based on the polarity of solute and solvent. Hence answer is option C) a solute with the same polarity as the solvent will dissolve.
Q4) Hexane and butane are hydrocarbons hence they are
miscible.
Water and methanol are polar solvents, hence they are
miscible.
Methanol and ethanol are also polar solvents hence they are
miscible.
Glycol and ethanol both are polar and have great hydrogen bonding,
so they are miscible.
Hexane is non-polar and water is a polar solvent. Hence they are
not miscible.
Thus the answer is option E) hexane and water.
Q5) An electrolyte is a substance that produces ions when
dissolved in water.
The answer is option D).

PART IV. MISCIBILITY OF TWO LIQUIDS
1. For the first two liquids in Table IV-B (the solvents in the
miscibility tests), use the molecular structures provided in the
Introduction to identify each liquid as polar or nonpolar. Put an X
in the appropriate column.
2. For the remaining liquids in Table IV-B, determine if they
are primarily polar, primarily nonpolar, or both polar and polar
based on your observations in Table III-A and based on the polarity
of the solvent....

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...

Hello, I need help solving the 3 parts of this question.
Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As...
