Solution
During vacuum filtration, the filter paper must be dampened with solvent for several reasons:
a. It ensures that the filtrate does not mix with the residue again during filtration. This is important because it helps to maintain the purity of the filtrate.
b. It ensures that the paper doesn’t absorb the filtrate during filtration. If the paper were to absorb the filtrate, it could potentially alter the results of the filtration process.
c. It ensures the paper adheres to the plate and keeps materials from passing under the paper. This is crucial for maintaining the integrity of the filtration process and ensuring that only the desired materials pass through the filter.
d. It ensures the paper adheres to the plate and keeps the filter paper from tearing. If the filter paper were to tear, it could allow unwanted materials to pass through, compromising the filtration process.
