Why Filter paper usually a poor material on which to powder a solid before introducing it to a capillary melting tube?

Filter paper can introduce impurities or substances that can affect the melting point determination of a solid when powdered on it, as filter paper itself may contain residues or impurities. Also, filter paper can absorb the sample, making it difficult to transfer and introduce it into a capillary melting tube accurately. It is better to use materials like glass plates or watch glasses for powdering solids before introducing them to a capillary melting tube to avoid such issues.

Wetting the filter before filtering out undissolved material is important because it helps to prevent the filter paper from absorbing the solvent, which can lead to loss of the dissolved substances. Pre-wetting ensures that the filter is fully saturated, allowing for a more efficient filtration process and reducing the risk of clogging. Additionally, it helps to create a better seal between the filter and the funnel, promoting effective separation of solid and liquid phases.
