What does the term heat of neutralization mean?
Abstract : Heat of neutralization means the heat of reaction resulting from the neutralization of an acid or base especially the quantity produced when a gram equivalent of a base or acid is neutralized with a gram equivalent of an acid or base in dilute solution .In this experiment, Alkaline X is used .
What is the amount of heat lost to a calorimeter?
The amount of heat lost to calorimeter is the difference between the heat lost by the warm water and that gained by the cool water. comparison to be made between these two different acids.
How is the total amount of heat produced by a chemical reaction measured?
Calorimeters are insulated to prevent loss or gain of heat between the calorimeter and its surroundings so that heat flow in the system can be measured. The total amount of heat that is produced or absorbed by a chemical reaction, at constant pressure, is called the enthalpy of reaction (ΔH).
