Question
f you had weighed out 0.070 - 0.080 g of ascorbic acid to make the standard ascorbic acid solution, what affect would that have on the determination of a DCP concentration?
You would need twice the amount of DCP solution to determine the concentration of DCP.
The concentration of DCP would have been twice as much what you calculated in the experiment.
You would calculate the same number of moles of ascorbic acid in the 10 mL you removed to dilute the standard ascorbic acid solution would have remained the same.
The concentration of DCP would have been 1/2 what you calculated in the experiment
A)You would need twice the amount of DCP solution to determine the concentration of DCP.
B)The concentration of DCP would have been twice as much what you calculated in the experiment.
C)You would calculate the same number of moles of ascorbic acid in the 10 mL you removed to dilute the standard ascorbic acid solution would have remained the same.
D)The concentration of DCP would have been 1/2 what you calculated in the experiment
Explanation / Answer
Solution :-
If you had weighed out 0.070 - 0.080 g of ascorbic acid to make the standard ascorbic acid solution
if this mass of ascorbic acid is twice the mass of ascorbic acid needed for the reaction 'then the DCP concetration would be twice than the actual concentration of the DCP
And if the 0.07 to 0.08 g of the ascorbic acid is half the mass of the ascorbic acid needed for the titration then the calculated concetration of the DCP would be half than the actual concentration of the DCP
