# Problem: You want to analyze a silver nitrate solution.You could add HCl(aq) to the solution to precipitate out AgCl(s). What volume of a 0.160 M HCl(aq) solution is needed to precipitate the silver ions from 16.0 mL of a 0.210 M AgNO3 solution?

###### FREE Expert Solution

We’re being asked to calculate the volume of a 0.160 M HCl(aq) solution is needed to precipitate the silver ions from 20.0 mL of a 0.210 M AgNO3 solution.

For this problem, we need to do the following steps:

Step 1: Write and balance a chemical equation for the given reaction.

Step 2: Determine the volume of HCl needed.

Step 1: Since HCl and AgNO3 are ionic compounds, they form ions when dissociating in water.

The dissociation of the two compounds is as follows:

For KCl: Hydrogen has a charge of +1. This means Cl- has a charge of –1:

HCl(aq)  K+(aq) + Cl(aq)

For AgNO3: Silver has a charge of +1. The nitrate ion has a charge of –1:

AgNO3(aq)  Ag+(aq) + NO3(aq)
