What is electronegativity? (see the figure in the pdf file in the moodle folder. The further right the more electroneg, the more up the more electroneg. Unusual properties of water: high heat capacity, amount of heat needed to raise temp of 1 gram of water by 1 deg. C: 1 cal per g of water, high heat of vaporization. Ice floats and benzene sinks: high dielectric (and how this affects solubility, good solvent, a crystal of table salt dissolving in water. Be able to manipulate ph and poh. ph= log [1/h+] =-log [h+] ph scale log base 10 the diff btw ph 3 and ph 4 is a 10-fold difference in the concentration of h+
