Document Summary
Lecture 1 intro/chemistry 08/01/18: electrons on outermost shell = most important, nucleus = most of atom weight, atomic # = # protons (so 2 in example below) 2he: 4 = mass # (will also see weighted average) = # p & n = daltons (unit = d, only electrons are important for bonding, valence electrons = unpaired electrons. Lecture 2 - chemistry 2 10/01/18: explains how to use library sources for research project. Water forces nonpolar molecules together, because doing so minimizes their disruptive effects on h-bonded water network. 10 ml 0. 5 m acetic acid titrated with. Lecture 3 proteins 15/01/18: titration curve. Initially 10ml 0. 5m acetic acid titrated with 0. 5m naoh: acid largely non-dissociated in beginning. In beginning ph rising very slowly because oh- combines with h+ to form water so it pushes dissociation of acetic acid. Important for stability/functionality of proteins: add equal parts molarity acetic acid & acetate to form buffer.
