Document Summary
Solvency: the ability to dissolve other chemicals, relationship with water, hydrophillip, water loving ii. Can dissolve in water: hydrophobic, water hating ii. Adhesion and cohesion: adhesion, tendency of one substance to stick to another, cohesion, tendency for substances to stick to itself, surface film, water molecules being held together by a force called v. Chemical reactivity surface tension: ability to participate in chemical reactions, water ionizes into h + and oh , water ionized other chemicals (acids and salts, hydrolysis and dehydration, hydrolysis i. The take away of water: thermal stability of water, heat capacity i. ii. The amount of heat required to raise the temperature of 1g of a substance by 1 degree celsius. High heat capacity: energy is used first to oppose h bonds, then the substance can increase, water receives a lot of energy and heat before those h bonds break iii.
