When a solution containing AGNO3 is mixed with a solution of NACl AgCl will precipitate because Q > Ksp. Silver chloride will precipitate out of solution, leaving an unsaturated solution of AgCl.
Explain molarity?
- A chemical species' concentration in a solution, specifically the amount of a solute per unit volume of solution, is measured by its molar concentration.
- The moles per litre, is expressed by the unit symbol mol/L or mol/dm3 in SI units.
Information provided according to:
As a result, AgNO3's molarity is 0.10 M.
Following that, NaCl's molarity is equal to 0.075 M.
Thus, Ksp AgCl is equal to 1.77 * 10^-10.
Then the variables in the equation are as follows:
AgNO3 + NaCl AgCl(s) + NaNO3 (aq)
Next, we have 0.10 moles of Ag+ for every 0.10 moles of AgNO3 (molarity is equal to 0.10 M).
Following that, we have 0.075 moles of Cl- (molarity is 0.075 M) for 0.075 moles of NaCl.
Now, we compute Q, which is:
So Q is = [Ag+][Cl-]
In the following, Q is equal to (0.10 M)(0.075 M) = 0.0075.
Currently, Ksp is 1.77 x 10-10.
Q >>> Ksp.
