Question
Which of the following statement best defines the term ‘salt’?
- Salt is formed when metal reacts with an alkali.
- Salt contains sodium ions and chloride ions.
- Salt is formed from a weak van der Waals’ force of attraction.
- Salt is formed when the hydrogen ions in acid are replaced by metal or ammonium ions.
Hint:
Salt is an ionic compound that has a cation other than H+ and an anion other than OH– and is obtained along with water in the neutralization reaction between acids and bases.
The correct answer is: Salt is formed when the hydrogen ions in acid are replaced by metal or ammonium ions.
- When an acid reacts with the base, the metallic ion present in the base removes the hydrogen ion.
- The metallic ion along with the non metallic ion form salt. The hydrogen ion and hydroxide ion together make water.
