Assay Master Interview Questions and Answers for Freshers

When NaCl is added to nitric acid, a chemical reaction occurs.

• NaCl dissociates into Na+ and Cl- ions in water

• Nitric acid dissociates into H+ and NO3- ions in water

• The Cl- ions from NaCl react with H+ ions from nitric acid to form HCl gas

• The NO3- ions from nitric acid react with Na+ ions to form sodium nitrate (NaNO3)

• The overall reaction can be represented as: NaCl + HNO3 -> HCl + NaNO3

Sodium is a chemical element with the symbol Na and atomic number 11.

• Sodium is a highly reactive metal.

• It is a soft, silvery-white alkali metal.

• Sodium is commonly found in table salt (sodium chloride).
