CHE 102 Study Guide - Molality, Solvation, Molar Concentration
Document Summary
Osmotic pressure: =imrt ( t = tsoln tsolvent) (( t = tsolvent - tsoln) Average rate: slope of line between 2 points. Initial rate method: use data to solve for m & n (lab 14) Graphical method: plot data and look for a straight line: 1st order: ln [a] vs t = straight line. Q = k (equilibrium); qk (shift to reactants) Temp: treat like a chemical (endothermic = reactant, exothermic = product) Pressure: shift to relieve, go to side with fewer gas. Conjucates: substance that has either gained or lost the h+ Bases: 8 metal hydroxides, also be aware of metal hydrides & metal nitrides. Acids: not on the list of 7 ha. Bases: nh3 & amines b + h2o. Weak acids/bases produce weak conjugates (that can react w/h2o) Polyprotic: multiple front hydrogens, only lose 1 at a time, each has a respective ka.
