Question

50 mL sodium phosphate solution with a concentration of 0.200 mol/L

50 mL magnesium nitrate solution with an unknown concentration.

Mass of filter paper: 0.15 g

Mass of filter paper and precipitate: 4.63 g


1. Calculate the percent deviation of your molar concentration of magnesium nitrate using the theoretical concentration of 0.15 mol/L.


2. Calculate the predicted mass of precipitate using the theoretical concentration of 0.15 mol/L for magnesium nitrate.


3. Calculate the percent yield of the experiment and explain why this yield is not 100%. 

Calculate the concentration of the unknown solution using the lab data.

1. Using a volumetric pipette, measure 50.0 mL of the Mg(NO,)2(aq) solution into a 100 mL beaker. 2. Slowly add the NajPO,(aq) to the solution in small amounts while swirling the beaker. Continue until no more precipitate is formed upon adding small amounts of Na;PO,(aq). 3. Set up your filtration apparatus, as shown below. Record the mass of your filter paper. Be sure to record the mass of the filter paper before folding and wetting it. 4. Filter the mixture through the filter paper and record the color of the precipitate. Wash the precipitate with small amounts of deionized water. 5. Remove the filter paper with the precipitate and place it on a watch glass. 6. Leave the sample to dry (one hour in an oven at 70 *C or overnight on the counter).
