Predict whether a chemical reaction occurs and write the balanced molecular equation.
Ag2SO4 (aq) + KCl (aq) →
A
Ag2SO4 (aq) + KCl (aq) → AgCl (s) + K2SO4 (aq)
B
Ag2SO4 (aq) + 2 KCl (aq) → 2 AgCl (s) + K2SO4 (aq)
C
Ag2SO4 (aq) + 2 KCl (aq) → 2 AgCl (aq) + K2SO4 (aq)
D
No reaction
Verified step by step guidance1
Identify the reactants and products in the given chemical equation: Ag2SO4 (aq) + KCl (aq) → AgCl (s) + K2SO4 (aq).
Determine the solubility of each compound in the reaction. Ag2SO4 is slightly soluble, KCl is soluble, AgCl is insoluble, and K2SO4 is soluble in water.
Use the solubility rules to predict the formation of a precipitate. Since AgCl is insoluble, it will precipitate out of the solution, indicating a chemical reaction occurs.
Write the balanced molecular equation by ensuring the number of atoms of each element is the same on both sides of the equation. Balance the equation: Ag2SO4 (aq) + 2 KCl (aq) → 2 AgCl (s) + K2SO4 (aq).
Verify the balanced equation by counting the atoms of each element on both sides: 2 Ag, 1 S, 4 O, 2 K, and 2 Cl on both sides, confirming the equation is balanced.
