Which statement about the process of dissolving is true?
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?
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?
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.
