Question

What is the balanced net ionic equation of mixed AgNO3 and MgCl2 solutions?Ag+(aq) + Cl2–(aq) → AgCl2(s)Mg2+(aq) + NO3–(aq) → Mg(NO3)2(s)Ag3+(aq) + 3Cl–(aq) → AgCl3(s)Ag+(aq) + Cl–(aq) → AgCl(s)

Answer 1

Ag⁺(aq) + Cl⁻ → AgCl(s)

Step-by-step explanation

The balanced molecular equation of mixed AgNO3 and MgCl2 solutions is:

2AgNO₃(aq) + MgCl₂(aq) → 2AgCl(s) + Mg(NO₃)₂ (aq)

The balanced complete ionic equation for the reaction is:

2Ag⁺(aq) + 2NO₃⁻(aq) + Mg²⁺(aq) + 2Cl⁻ → 2AgCl(s) + Mg²⁺(aq) + 2NO₃⁻(aq)

NO₃⁻ ions and Mg²⁺ are spectators, remaining in the solution. Ag⁺ and Cl⁻ ions react to form a precipitate of AgCl according to this net ionic equation below.

The balanced net ionic equation is:

Ag⁺(aq) + Cl⁻ → AgCl(s)
