Formation of Anions from Complete Dissociation

When a compound undergoes complete dissociation, it means that all of its molecules break apart into their constituent ions. In this case, we are considering the formation of anions from the complete dissociation of different compounds. Let's examine the compounds mentioned in the question:

a) Phosphate Sodium (Na3PO4): - When sodium phosphate undergoes complete dissociation, it forms three sodium ions (Na+) and one phosphate ion (PO4^3-). - The phosphate ion (PO4^3-) is an example of an anion, as it carries a negative charge.

b) Aluminum Nitrate (Al(NO3)3): - Complete dissociation of aluminum nitrate results in one aluminum ion (Al^3+) and three nitrate ions (NO3^-). - The nitrate ion (NO3^-) is an example of an anion.

c) Iron Chloride (FeCl2): - Iron chloride dissociates into one iron ion (Fe^2+) and two chloride ions (Cl^-). - The chloride ion (Cl^-) is an example of an anion.

d) Calcium Hydroxide (Ca(OH)2): - Complete dissociation of calcium hydroxide yields one calcium ion (Ca^2+) and two hydroxide ions (OH^-). - The hydroxide ion (OH^-) is an example of an anion.

To summarize, the anions formed from the complete dissociation of the compounds mentioned are: - Phosphate ion (PO4^3-) from sodium phosphate (Na3PO4). - Nitrate ion (NO3^-) from aluminum nitrate (Al(NO3)3). - Chloride ion (Cl^-) from iron chloride (FeCl2). - Hydroxide ion
