Questions and Answers

Which statement about the process of dissolving is true?

All solutes are soluble in all solvents.

Dissolving is an endothermic process only.

Solutes always dissolve better in polar solvents.

Like dissolves like implies that similar polarities enhance solubility. (correct)

What characterizes a saturated solution?

No additional solute can dissolve in the solvent at a given temperature. (correct)

All solute particles have formed precipitates.

The concentration of solute is extremely low.

It can still dissolve more solute until a specific quantity is reached.

In preparing a standard solution from a concentrated liquid, which formula is used?

$c_1V_1 = c_2V_2$ (correct)

$c_1V_2 = c_2V_1$

$c_1V_1 = c_2V_1$

$c_2V_1 = c_1V_2$

Study Notes

Solutions and Solubility

Solutions classification: Factors include solubility, homogeneity, solute, solvent, concentration, aqueous, miscible, immiscible, saturated, supersaturated, and unsaturated
Dissolving compounds: The process follows the principle: "Like dissolves like"
Solubility curves: Graphs showing the relationship between temperature and the amount of solute that can dissolve in a solvent. They display saturated, unsaturated, and supersaturated states
Solution concentration: Various methods, including percent concentration (ppm, ppb, ppt), and molar concentration
Standard solution preparation: Calculations and steps for preparing solutions from solids or liquids (dilution). The formula c₁V₁ = c₂V₂ is used.
Stoichiometry of solutions: This involves using chemical equations and calculations with solutions
Acids and bases: Properties of weak and strong acids and bases; different concentrations (dilute and concentrated), and titration techniques.
