Consider this reaction. Na raised to the plus plus cap c power sub 2 cap h sub 3 cap o sub 2 raised to the negative aq power plus cap h raised to the plus plus Cl raised to the negative right arrow cap n raised to the plus plus Cl raised to the negative plus HC power power sub 2 cap h sub 3 cap o sub 2 power power Which is the net ionic equation for the reaction?
Answer
A
Na raised to the plus plus Cl raised to the negative right arrow NaCl power power
B
Na raised to the plus plus cap c power sub 2 cap h sub 3 cap o sub 2 raised to the negative right arrow NaC sub 2 cap h sub 3 cap o sub 2 power
C
cap h raised to the plus plus Cl raised to the negative right arrow HCl power power
D
cap c sub 2 cap h sub 3 cap o sub 2 raised to the negative aq power plus cap h raised to the plus right arrow HC sub 2 cap h sub 3 cap o sub 2 power
Explanation
Sodium acetate and hydrochloric acid dissociate into ions in water. The Na⁺ and Cl⁻ ions remain unchanged on both sides, so they are spectator ions and cancel. The net ionic equation is C₂H₃O₂⁻(aq) + H⁺(aq) → HC₂H₃O₂(aq), which is choice D.
