Question
Will a precipitate form when 0.02 L of 0.1M AgNO3 is added to 0.1 L of 0.1M NaCl? (Ksp of AgCl = 1.77 x 10-10)Yes, because Q > Ksp.Yes, because Q < Ksp.Yes, because Q is equal to Ksp.No, because Q < Ksp.
Solution
To answer this question, we first need to understand what the terms Ksp and Q represent.
Ksp is the solubility product constant. It represents the maximum amount of a salt that can dissolve in a solution at a given temperature.
Q, or the reaction quotient, is a measure of the relative amounts of products and reactants present during a reaction at a particular point in time.
In this case, we are looking at the reaction of AgNO3 and NaCl to form AgCl and NaNO3. The reaction can be written as follows:
AgNO3 + NaCl -> AgCl(s) + NaNO3
The Ksp expression for this reaction is [Ag+][Cl-] = Ksp
The Q expression for this reaction is [Ag+][Cl-] = Q
We are given that the Ksp of AgCl is 1.77 x 10^-10.
We are also given the volumes and molarities of the AgNO3 and NaCl solutions. We can use these to calculate the concentrations of Ag+ and Cl- ions in the solution after the reaction.
The number of moles of AgNO3 is (0.02 L)(0.1 mol/L) = 0.002 mol.
The number of moles of NaCl is (0.1 L)(0.1 mol/L) = 0.01 mol.
Since the reaction goes to completion, all of the AgNO3 and NaCl will react, so the final concentrations of Ag+ and Cl- ions will be:
[Ag+] = 0.002 mol / 0.12 L = 0.0167 M [Cl-] = 0.01 mol / 0.12 L = 0.0833 M
So, Q = (0.0167)(0.0833) = 1.39 x 10^-3
Since Q > Ksp, a precipitate will form. So, the correct answer is "Yes, because Q > Ksp."
