Question

Which of the following is considered the net ionic equation for the Limiting Reagent Experiment?

A. CaCl2(aq) + Na2CO3(aq) $LaTeX: \longrightarrow$ ? CaCO3(s) + 2NaCl(aq)

B. Ca2+(aq) + 2Cl-(aq) + 2Na+(aq) + CO32-(aq) $LaTeX: \longrightarrow$ ?CaCO3(s) + 2Na+(aq) + 2Cl-(aq)

C. Ca2+(aq) + CO32-(aq) $LaTeX: \longrightarrow$ ?CaCO3(s)

D. Na+(aq) +Cl-(aq) $LaTeX: \longrightarrow$ ?NaCl(aq)

Answer 1

In net ionic equation, aqueous component should be present as ions and not as molecules

So, A is wrong

In net ionic equation, there should be no common ions on both sides

in B we have common ions as Na+ and Cl-

So, B is wrong

C is correct

In net ionic equation, aqueous component should be present as ions and not as molecules

So, D is wrong

Answer: C
