Predict whether or not a precipitate forms upon mixing 175.0 mLmL of a 0.0055 MKClMKCl solution with 145.0 mLmL of a 0.0015 MM AgNO3AgNO3 solution. Identify the precipitate, if any.

Answer : The precipitate is, AgCl.

Explanation :

The balanced chemical reaction will be:

First we have to calculate the molarity of ion.

where,

are the initial molarity and volume of KCl.

are the final molarity and volume of ion.

We are given:

Putting values in above equation, we get:

Now we have to calculate the molarity of ion.

where,

are the initial molarity and volume of .

are the final molarity and volume of ion.

We are given:

Putting values in above equation, we get:

Now we have to calculate the value of reaction quotient.

The expression for reaction quotient will be :

Now put all the given values in this expression, we get

The given solubility constant value is,

When ; the reaction is product favored.  (No precipitation)When ; the reaction is reactant favored.  (Precipitation)When ; the reaction is in equilibrium. (Sparingly soluble)

As, then the reaction is reactant favored that means formation of precipitation.

Thus, the precipitate is, AgCl.
