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, she filters, washes and weighs it, and finds that has been produced. The balanced chemical equation for the reaction is:Cl(aq) + AgNO3(ag)------- AgCl(s) + NO3- (ag) o What kind of reaction is this? a. acid-base b. redox orvcap c. precipitation

Answer 1

Answer:

c. precipitation

Explanation:

Let's consider the following balanced net ionic equation.

Cl⁻(aq) + AgNO₃(ag) ⇒ AgCl(s) + NO₃⁻ (ag)

What kind of reaction is this?

a. acid-base. No, because the reactants are not acids and bases.

b. redox. No, because all the species have the same oxidation numbers in the reactants and the products

c. precipitation. Yes, because an insoluble compound (AgCl) is produced, which then precipitates.
