What is the balanced chemical equation for the dissolution of copper(II) sulfate in water?
A
CuSO4 (s) + H2O (l) → CuO (s) + H2SO4 (aq)
B
CuSO4 (s) → Cu^2+ (aq) + SO4^2- (aq)
C
CuSO4 (s) + H2O (l) → Cu^2+ (aq) + SO4^2- (aq)
D
CuSO4 (s) + H2O (l) → CuSO4 (aq)
Verified step by step guidance1
Identify the chemical species involved in the dissolution of copper(II) sulfate in water. Copper(II) sulfate is represented as CuSO4, and water is H2O.
Understand that dissolution involves the separation of the ionic compound into its constituent ions when it is dissolved in water. Copper(II) sulfate will dissociate into copper ions (Cu^2+) and sulfate ions (SO4^2-).
Write the chemical equation for the dissolution process. Start with the solid copper(II) sulfate (CuSO4) and water (H2O) as reactants.
Express the products of the dissolution. The copper(II) sulfate will dissociate into copper ions (Cu^2+) and sulfate ions (SO4^2-) in aqueous solution.
Combine the reactants and products to form the balanced chemical equation: .
