1
Q
Neutralisation
A
neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
2
Q
Exothermic
A
An exothermic reaction is a “reaction for which the overall standard enthalpy change ΔH⚬ is negative.” Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.
3
Q
Endothermic
A
Accompanied by or requiring the absorption of heat.
