Lesson 415 of 1524
Solutions and Colloids
The solutes are the other components typically present at concentrations less than that of the solvent.
Practice this chapterThe solutes are the other components typically present at concentrations less than that of the solvent. Electrolytes may be covalent compounds that chemically react with water to produce ions (for example, acids and bases), or they may be ionic compounds that dissociate to yield their constituent cations and anions, when…
Dissolution of an ionic compound is facilitated by ion-dipole attractions between the ions of the compound and the polar water molecules. A solution forms when two or more substances combine physically to yield a mixture that is homogeneous at the molecular level.
colloid — (also, colloidal dispersion) mixture in which relatively large solid or liquid particles are dispersed uniformly throughout a gas, liquid, or solid. ionic compound — facilitated by ion-dipole attractions between the ions of the compound and the polar water molecules. solutes — the other components typically present at concentrations less than that of the solvent. solvent — the most concentrated component and determines the physical state of the solution.
Worked example
What does “colloid” mean in Solutions and Colloids?
- 1Use the wording this chapter gives for colloid.
- 2The book says: (also, colloidal dispersion) mixture in which relatively large solid or liquid particles are dispersed uniformly throughout a gas, liquid, or solid.
- 3Do not use the meaning of ionic compound. That term means facilitated by ion-dipole attractions between the ions of the compound and the polar water molecules.
Result: (also, colloidal dispersion) mixture in which relatively large solid or liquid particles are dispersed uniformly throughout a gas, liquid, or solid
Why. That is the meaning this chapter gives for colloid.
Do not swap colloid and ionic compound. colloid means (also, colloidal dispersion) mixture in which relatively large solid or liquid particles are dispersed uniformly throughout a gas, liquid, or solid. ionic compound means facilitated by ion-dipole attractions between the ions of the compound and the polar water molecules.
