Document Summary
Chem 1a03 lecture 8 oct 17 water and aqueous solution. Strong salvation properties for most polar molecules/ions: solubization of polar/ionic solutes: hydration, energetically favorable h2o solute interactions. Ion hydration, sodium pumps + ion transport, protein folding, activity and drug. Auto-ionization of water: water is amphoteric and conductive acts as an acid and a base with itself to produce hydronium and hydroxide. ph = -log[h3o] = 7. 0. Major types of aqeuous chemical reactions: k is a measure of extent of rxn and transformation: solubility or precipitation reactions: (ion transfer) lab 2. Cu(no3)2(aq) + 2 naoh(aq) : reduction-oxidation (redox) reactions: transfer) lab 2. Zn (s) + cu2+ (aq) zn2+ (aq) + cu (s: acid-base reactions: (proton transfer) Most salts containing alkali metal or ammonium cations are soluble. , and are soluble, except with metals such as. 4 salts with +1 cations and insoluble. are soluble, but with most +2 cations these salts are.
