Document Summary
Titration- trying to figure out how much concentration of a substance is in a mixture by using a known amount of substance. Equivalence point- point in titration at which one reactant has been exactly consumed by addition of the other reactant. Primary standard- a pure, solid acid or base that can be accurately weighed for preparation of a titrating reagent. Energy: capacity to do work or transfer heat. Work: force involved to move an object, organaized energy (w=f*d) Mechanical energy: sum of potential and kinetic as a whole. Thermal: sum of ke + pe of all atoms within. Kinetic energy: ke = (1/2)mv2 , where v is velocity. Closed system: energy but not matter can be passed to or from surroundings. Release energy in form of heat to surroundings. Burning wood, your body processing food, rain forming from gaseous water. Absorb energy in form of heat from surroundings.
