2.  What do you mean by neutralization reaction? Give two examples.​

Answer 1

Hope the answer helps...Pls mark as brainliest! Happy Learning!!

Step-by-step explanation:

1) Plaster of Paris should be stored in a moisture-proof container because the Plaster of Paris, a powdery mass, absorbs water (moisture) from the environment to form a hard solid substance known as Gypsum

2)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. The neutralization of a strong acid and strong base has a pH equal to 7.  Examples:

HCl. +NaOH -------> NaCl. +H2O

H2SO4 + Ca(OH)2 --------> CaSO4 +H2O
