While filtering the CaCO₃, a student notices that the filtrate is white. What is the likely reason, and what effects would this have on the results?
a) The likely reason is impurities in the original mixture, and this would affect the purity of the separated CaCO₃.
b) The likely reason is a chemical reaction occurring during filtration, and this would enhance the effectiveness of the separation process.
c) The likely reason is insufficient filtration, and this would result in contamination of the filtrate.
d) The likely reason is an error in the experimental procedure, and this would invalidate the entire experiment.
