A substance's solubility product, Ksp, is the mathematical product of its dissolved ion concentrations with each concentration raised to the power of their stoichiometric coefficients.
For example the solubility product of ionic compound Ag2S is
Ksp =[Ag+]2[S-2]

- Bond order is inversely proportional to the bond length and directly proportional to the dissociation energy.
- The greater the order of the bond, the greater is the stability of molecules.
- The greater the order of the bond, the shorter is the length of the bond.

Absolute Zero is defined as minimum absolute temperature of an ideal gas.
- If we plot pressure versus temperature we get a straight line and if weextend the line backwards to the x-axis as shown in the graph below. The minimumtemperature is found to be 273.15 °C (experimentally) andthis value is known as absolute zero.
- The relation between the temperature in kelvin and in Celsius scale is given by
T = tC + 273.15

| Perfect oligopoly | Imperfect oligopoly |
| If the firms produce the homogeneous the product then it is called perfect oligopoly. | If the firm produces differentiated products then it is called imperfect oligopoly. |
| It is rare to find this type of situation. Examples: cement, steel, aluminium and chemical producing industries |
Examples: Passenger cars, cigarettes and soft drinks. |

Water gas shift reaction involves water vapor reaction with carbon monoxide to give carbon dioxide and hydrogen gas. The reaction is
CO + H2O → CO2 + H2
Felice Fontana discovered this water gas shift reaction in 1780. It was made in England in the year 1828. The water gas was produced by blowing steam through red hot coke, the reaction is
C + H2O → CO + H2
