which of the following represents neutralisation reaction is exothermic
Answers
Explanation:
Neutralization is a chemical reaction, also called a water forming reaction, in which an acid and a base or alkali (soluble base) react and produce a salt and water solution (H
2
O). In other words, it can be said that neutralization is the combination of hydrogen ions H
+
and hydroxide ions OH
−
(or oxide ions O
2
) to form water molecule H
2
O. In the process, a salt is formed. In the process of neutralization a proton (usually hydrogen) is transferred. An acid is a proton donor, while a base is a proton receiver. H
2
O can act as either an acid or a base, depending on whether it comes in contact with an acid or a base; it takes the opposite form. Neutralization is generally exothermic, meaning it produces heat.
Answer:
Combustion or burning is a high-temperature exothermic redox chemical reaction between fuel and oxidant oxygen. Bond breaking requires energy to be supplied for bond dissociation so it is an endothermic process while bond formation releases energy so that the product becomes stable which is an exothermic process.Thus, the neutralization of phenol with sodium hydroxide is highly exothermic.
