Description
LECTURE 6 Solutions Slide No. Notes 1 - dilute not much solute - concentrated lots of solute - saturated maximum amount of solute dissolved - unsaturated less than maximum amount of solute dissolved - supersaturated produced by heating the solution, dissolving more solute, then letting it cool 2 - molality is independent of temperature 3 - 1.45g (mol342.3g) (30.0ml)(1.00gmol)(kg1000g) = 0.141 molkg 4 - miscible = can be mixed together in any proportions 5 - network solids ex. diamonds insoluble in all solvents - metals insoluble in liquid solvents; can dissolve in other metals - ex. brass = zinc and copper - ionic solids will dissolve if solvent has dipole-ion interactions strong enough - molecular solids will dissolve in solvent with same type of intermolecular forces - ex. glucose can H-bond with water 6 - Ans1: C - Ans2: B depends on substance - Ans3 gas solubility decreases 7 - pushin
