Question

Write an equation for the formation of each of the silver halides from their respective sodium salts and AgNO3

Answer 1

a)

aqueous solution of Silver nitrate reacts with aqueous solution of sodium chloride to form white precipitate of Silver chloride.

AgNO3(aq) + NaCl(aq) ------------------- AgCl(s) + NaNO3(aq)         Molecular equation  

Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) -------------- AgCl(s) + Na+(aq) + NO3-(aq)     ionic equation

Spectator ions Na+ and NO3- are cancelled on both sides

Ag+(aq) + Cl-(aq) ------------- AgCl(s)              Net ionic equation

b)

aqueous solution of Silver nitrate reacts with aqueous solution of sodium Bromide to form pale yellow precipitate of Silver Bromide..

AgNO3(aq) + NaBr(aq) ------------------- AgBr(s) + NaNO3(aq)        Molecular equation  

Ag+(aq) + NO3-(aq) + Na+(aq) + Br-(aq) -------------- AgBr(s) + Na+(aq) + NO3-(aq)      ionic equation

Spectator ions Na+ and NO3- are cancelled on both sides

Ag+(aq) + Br-(aq) ------------- AgBr(s)        Net ionic equation

c)

aqueous solution of Silver nitrate reacts with aqueous solution of sodium Iodide to form yellow precipitate of Silver Iodide.

AgNO3(aq) + NaI(aq) ------------------- AgI(s) + NaNO3(aq)      Molecular equation

Ag+(aq) + NO3-(aq) + Na+(aq) + I(aq) -------------- AgI(s) + Na+(aq) + NO3-(aq)    ionic equation

Spectator ions Na+ and NO3- are cancelled on both sides

Ag+(aq) + I-(aq) ------------- AgI(s)     Net ionic equation
