Question

In this limiting reactant experiment, the accuracy of results depends on how well the students perform the various laboratory techniques.

From the list of steps and lab techniques below,

     A-  Vacuum filtration
     B - Precipitate weighing
     C - Measuring volume of reactants in two separate flasks
     D - Drying precipitate in the oven
     E - Heating of solutions inside the hood
     F - Mixing of two hot solutions inside the hood and further heating

(a) Arrange these lab techniques/steps in the order they are performed to complete this experiment. (0.5 pt.)

(b) What is this overall analytical technique called? (0.5 pt.)

Answer 1

To complet this experiment go for the following order

1] Measuring the reactant in two separate flask

Then ones we know the volume heat the solution so

2] Heating of solution inside the hod

After heating of solution

3] Mixing of two hot solutions inside the hood and further heating

When two solution is mixed under a hot condition inside the hood reaction is procided and formation of product in the form of precipate

4] Vaccum Filteration

Separation of precipate takes place

5] Drying the precipate in the oven

To remove the moisture kept the ppt in to the oven

6] Precipated weight

To know the exact weight we go for to take weight

B] The over all analytical technique is the Gravemetric estimation
