Gross Calorific Value is the amount of heat released by the complete combustion of a unit quantity of a fuel.

• It is a measure of the total amount of energy produced when a fuel is completely burned.

• Usually expressed in units of energy per unit mass, such as kJ/kg or Btu/lb.

• Helps in determining the efficiency of a fuel for energy production.

• Higher Gross Calorific Value indicates a more efficient fuel.

• Example: The Gross C

Potentiometric titration is a method of chemical analysis that measures the voltage change in a solution as a titrant is added.

• Potentiometric titration involves measuring the potential difference between a reference electrode and a measuring electrode as titrant is added to the solution.

• The endpoint of the titration is determined by a sudden change in voltage, indicating the completion of the reaction.

• Common applicatio...read more
