How does temperature affect neutralization

WebThe Scottish physician Joseph Black, was the first to recognise the distinction between heat and temperature, and is said to be the “Founder of Calorimetry”. ... Similarly the heat of neutralisation of a base is the amount of heat evolved when 1 g equivalent of the base is completely neutralised by a strong acid in a dilute solution. Or . WebA neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H + ions and OH – ions which form water. A neutralisation reaction is generally an acid-base neutralization reaction.
