When AgNO₃(aq) and NaCl(aq) are mixed, a white precipitate forms. The net ionic equation is

  • A

    AgNO₃ + NaCl → AgCl + NaNO₃

  • B

    Ag⁺(aq) + Cl⁻(aq) → AgCl(s)

  • C

    All ions are spectators

  • D

    Na⁺ + NO₃⁻ → NaNO₃

Explanation

Spectator ions (Na⁺, NO₃⁻) are removed; only the species that actually combine remain.
