Document Summary
Common ion effect the addition of an ion from another source. Solution ph where there is a weak acid or base. In a solution of a salt ab, addition of a additional b ions from another source will cause [a] to decrease because of ksp. Energy is conserved; it can be neither created nor destroyed. In an isolated system, natural processes are spontaneous when they lead to an increase in disorder, or entropy. The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero. Work w can be done on the system by the surroundings (or vice versa). It can take the form of mechanical work or of electrical energy transfer. Heat q flows from the system to the surroundings (or vice versa) Heat capacity of a substance describes the amount of heat that can be absorbed by the substance for a given unit rise in temperature.
