Which of the following is the balanced complete ionic equation for the reaction K2SO4(aq) + CaI2(aq) → CaSO4(s) + 2KI(aq)?
A
K2SO4(aq) + CaI2(aq) → Ca^2+(aq) + SO4^2-(aq) + 2K+(aq) + 2I-(aq)
B
2K+(aq) + SO4^2-(aq) + Ca^2+(aq) + 2I-(aq) → Ca^2+(aq) + SO4^2-(aq) + 2K+(aq) + 2I-(aq)
C
K2SO4(aq) + CaI2(aq) → CaSO4(s) + 2K+(aq) + 2I-(aq)
D
2K+(aq) + SO4^2-(aq) + Ca^2+(aq) + 2I-(aq) → CaSO4(s) + 2K+(aq) + 2I-(aq)
Verified step by step guidance1
Identify the reactants and products in the given chemical equation: K2SO4(aq) + CaI2(aq) → CaSO4(s) + 2KI(aq).
Write the dissociation of the aqueous compounds into their respective ions: K2SO4(aq) dissociates into 2K+(aq) and SO4^2-(aq); CaI2(aq) dissociates into Ca^2+(aq) and 2I-(aq).
Recognize that CaSO4(s) is a solid and does not dissociate into ions in the solution.
Combine the ions from the reactants to form the complete ionic equation: 2K+(aq) + SO4^2-(aq) + Ca^2+(aq) + 2I-(aq) → CaSO4(s) + 2K+(aq) + 2I-(aq).
Verify that the equation is balanced by ensuring the number of each type of ion is the same on both sides of the equation.
