Question

to measure the amount of chlorine in a well-boring fluid, an analytical chemist adds silver nitrate solution to a sample of the fluid and collects the solid silver chloride product. when no more is produced, he filters, washes and weighs it, and finds that has been produced.the balanced chemical equation for the reaction is:

Answer 1

Type of reaction: Precipitation reaction

Precipitate: AgCl

Base: None

Element oxidized: None

Mass percent of chlorine in the sample: 100%

The reaction is a precipitation reaction because it produces a solid precipitate (AgCl) when two aqueous solutions are mixed.

The precipitate is AgCl because it is the only product that forms when Cl- and Ag+ ions react in aqueous solution.

There is no base in the reaction because neither of the reactants is a base.

There is no element oxidized in the reaction because neither of the reactants is oxidized.

The mass percent of chlorine in the sample is 100% because all of the chlorine in the sample is precipitated as AgCl.

The balanced chemical equation for the reaction is:

Cl (aq) + AgNO3(aq) → AgCl(s) + NO3 (aq)

This is a precipitation reaction because a solid (AgCl) is formed from two aqueous solutions.

The mass of chlorine in the sample is equal to the mass of silver chloride produced, since the mole ratio of Cl to AgCl is 1:1.
