The compound aluminum acetate is a strong electrolyte. Write the reaction when aluminum acetate is put into water: The Correct Answer and Explanation is : When aluminum acetate (( \text{Al(C₂H₃O₂)₃} )) is dissolved in water, it dissociates into its constituent ions, behaving as a strong electrolyte. The dissociation reaction can be written as: [\text{Al(C₂H₃O₂)₃ (aq)} […]

 The compound calcium acetate is a strong electrolyte. Write the reaction when solid calcium acetate is put into water The Correct Answer and Explanation is : When solid calcium acetate (Ca(C₂H₃O₂)₂) is dissolved in water, it dissociates completely into its ions, as it is a strong electrolyte. The dissociation reaction can be written as follows:
