explain the following term with an example(a) neutralisation reactions (b) themite reaction
Answers
Answer:
(a) A neutralization reaction is when an acid and a base react to form water and salt and involves the combination of hydrogen ions and hydroxyl ions to generate water.
Example – 1: When Sodium hydroxide is added to hydrochloric acid. Sodium chloride and water are formed.
NaOH+HCl⟶NaCl+H2O
(b) A thermite reaction is basically iron oxide (rust) reacting with aluminum to produce molten iron. The products are aluminium oxide, elemental iron, and a large amount of heat. The reactants are commonly or thermite mixture is aluminum powder and iron oxide (rust) powder. When the mixture is heated, it starts reacting as the aluminum is more reactive than the iron and aluminium forms stronger and stable bonds with oxygen than iron.
Example- Fe203 +2Al --> Al2O3 +2Fe
