Why Iron chloride acidic while sodium carbonate basic explain?

Answer 1

Iron chloride is acidic because some of the water molecules in its hydration shell deprotonate. Sodium carbonate is basic because its the salt of a weak acid. Thus, some carbonate ions take protons from water, creating basic hydroxide ions.

Answer 2

Iron chloride is acidic because when dissolved in water, it forms hydrochloric acid which increases the concentration of protons in the solution. Sodium carbonate is basic because it dissociates in water to form carbonate ions, which can react with water to form hydroxide ions, increasing the concentration of hydroxide ions and making the solution basic.
