M Review | Constants | Periodic Table - Part A When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A) is represented as What is the pH of a buffer prepared by adding 0.405 mol of the weak acid...

For gaseous reactions another form of the equilibrium constant, Kp, is calculated from parlial pressures instead of concentrations. These two equilibrium constants are related by the equation K = K (RT) where R=0.08206 Latin/(K. Inol), T is the absolute temperature, and An is the change...

MI Review | Constants Periodic Table Part A The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. Phosgene (carbonyl chloride), COCl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. Phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: For a gaseous reaction with the general form aA + bB =cC + dD CO(g)...

Review | Constants Periodic Table Part A Calorimetry is a method used to measure changes in enthalpy, or heat, that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant volume or "bomb") calorimeters. Bomb calorimeters are used to measure combustion and other gas- producing reactions, in which the reaction is observed in a strong, sealed vessel. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer, in which energy changes in a...
