CHM 1046 Lecture Notes - Lecture 28: Supersaturation, Ionic Compound, Network Covalent Bonding
Document Summary
Solids whose composite units are molecules (low m. p. ) Solids held together by metallic bonds (variable m. p. ) Solids held together by cations and anions (high mp. ) Solids held together by covalent bonds (highest mp) ex: graphite. Solution: homogeneous mixture of two or more substances (solute + solvent) Solute: component in smaller amount; solvent: component in greater amount. What does it mean to say that a substance is soluble in another substance. A substance is soluble in another substance if a given amount of substance dissolves in a given amount of solvent. What does the statement like dissolves likemean with respect to solution formation. Polar solvents tend to dissolve many polar or ionic solutes. Nonpolar solvents tend to dissolve many nonpolar solutes. Saturated: the dissolved solute is in dynamic equilibrium with the solvent. Unsaturated: additional solute can be added to a solution and it will dissolve. Supersaturated: an unstable solution with excess solute dissolved in it (obtained by heating.
