What happens when you combine silver nitrate with sodium chloride?

Answer 1

The solution will first form a white precipitate, then eventually turn black.

Combining silver nitrate # AgNO_3# with sodium chloride #NaCl# is a double replacement reaction. The positive and negative ions trade places. See the chemical reaction below

# Ag^+(aq) + NO_3^(-) (aq) + Na^(+)(aq) + Cl^(-)(aq) -> AgCl(s) + Na^(+)(aq) + NO_3^(-)(aq)#

The sodium ion #(Na^+)# and the nitrate ion #(NO_3^(-))# do not react and stay in the solution as spectator ions.

The silver ion #Ag^+# combines with the chloride ion #Cl^(-)# to form insoluble silver chloride (AgCl) which is white; it turns the solution black when the solute is exposed to light.

When you combine silver nitrate with sodium chloride, a chemical reaction occurs, resulting in the formation of solid silver chloride (AgCl) and aqueous sodium nitrate (NaNO3). This reaction is represented by the chemical equation:

AgNO3(aq) + NaCl(aq) -> AgCl(s) + NaNO3(aq)

The silver chloride formed is insoluble in water and precipitates out as a white solid, while sodium nitrate remains dissolved in the solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
