Answer :
A semi-permeable paper barrier called filter paper is positioned perpendicular to an air or liquid flow. It is employed to separate tiny solid particles from gases or liquids.
What is the name of the paper filter?
Paper and cellulose filters are made from cellulose fibers and are intended for general filtration. That particle retention level might be as low as 2.5 m. This kind of membrane filter must be folded in order to be used in simple gravity filtering using a plastique or glass filtration funnel.
What's the clearest filter paper?
For critical gravimetric analysis, this grade serves as a global benchmark. Of all the Whatman cellulose filter papers, it is renowned for having the best particle retention.

Final answer:
Litmus paper, a type of filter paper, acts as a pH indicator by changing color in response to the pH of the environment. It turns red in acidic environment, blue in basic environments, and remains unaltered in neutral substances. It thus allows quick and easy determinations of substance pH level.
Explanation:
The appearance of filter paper, specifically litmus paper, changes depending upon the pH of the environment it is introduced to. Litmus paper, for instance, is a type of filter paper that's been treated with a water-soluble dye. In contact with substances of varying pH levels, this dye triggers a color change in the litmus paper, providing a visual indicator of the substance's pH value.
For instance, when litmus paper comes into contact with an acidic substance, it turns red. In contrast, it turns blue when it comes into contact with a base. Neutral substances, like pure water, do not alter the color of litmus paper.
This function of litmus paper thus presents a straightforward method for determining whether a liquid solution is acidic, basic, or neutral. By using the pH indicator properties of litmus, or similar specialized filter papers, one can assess the pH level of different substances quickly and easily.
