Answer to Question #251277 in General Chemistry for putus

Question

Group 2: 25 mL CaCl₂

Trial Mass of filter paper Mass of solid + filter paper

1 0.65 g 1.48 g

2 0.64 g 1.57 g 

3 0.66 g 1.61 g

Our filtrate was a bit cloudy to start with, but didn't change at all when we added more of either starting material.

Based on the recorded notes from group 2, what alteration from the suggested procedure could account for the discrepancy in their data? Explain the evidence that led to your answer.

Answer 1

There were some discrepancies in the data.

These might be because of the givena bit cloudy filter paper.

So if we dry the filter paper properly we can eliminate these discrepancies.
