Heat Of Neutralization Flashcards
What is heat neutralization?
Heat neutralization is the process of counteracting or reducing heat generated during a chemical reaction.
True or False: Heat neutralization can only occur in exothermic reactions.
False
What are common methods to achieve heat neutralization?
Common methods include using heat exchangers, adding coolants, and employing endothermic reactions.
Fill in the blank: The reaction of _______ and _______ can be used for heat neutralization.
calcium carbonate, hydrochloric acid
What is the equation for the neutralization of hydrochloric acid with sodium hydroxide?
HCl + NaOH → NaCl + H2O
What type of reaction is heat neutralization typically classified as?
It is typically classified as a thermochemical reaction.
Which equation represents the endothermic reaction involved in heat neutralization?

True or False: All neutralization reactions release heat.
False
What is the purpose of using a coolant in heat neutralization?
The purpose is to absorb excess heat and maintain a stable temperature.
Which substance is commonly used as a coolant in chemical processes?
Water or ethylene glycol
What is the significance of the enthalpy change in heat neutralization?
It indicates the amount of heat absorbed or released during the reaction.
Fill in the blank: The reaction of _______ and _______ is an example of heat neutralization.
