Question

question 3 of 25
what is the complete ionic equation for the reaction between na₂so₄ and cacl₂?
a. 2na⁺(aq) + so₄²⁻(aq) + ca²⁺(aq) + 2cl⁻(aq) → caso₄(s) + 2na⁺(aq) + 2cl⁻(aq)
b. 2na⁺(aq) + 2cl⁻(aq) → 2nacl(aq)
c. na₂so₄(aq) + cacl₂(aq) → caso₄(s) + 2nacl(aq)
d. so₄²⁻(aq) + ca²⁺(aq) → caso₄(s)

Explanation:

Answer:

A. \(2Na^{+}(aq)+SO_{4}^{2 - }(aq)+Ca^{2+}(aq)+2Cl^{-}(aq)\to CaSO_{4}(s)+2Na^{+}(aq)+2Cl^{-}(aq)\)
