What is the difference between ashless and qualitative filter paper?\u003C/strong\u003E\u003Cbr /\u003EAshless (quantitative) filter papers are washed with acid to remove impurities, leaving an ash content of less than 0.01%. They are used for precise gravimetric analysis. Qualitative papers are used for general clarification where the weight of the residue is not critical.\u003C/p\u003E\u003Cp\u003E\u0026nbsp;\u003C/p\u003E\u003Cp\u003E\u003Cstrong\u003E2. How do pH-Fix strips differ from standard litmus paper?\u003C/strong\u003E\u003Cbr /\u003EpH-Fix strips feature dye molecules that are chemically bonded to the cellulose fiber. This prevents the dye from \u0022bleeding\u0022 into the sample, protecting the sample from contamination and ensuring a clear, accurate color comparison even in weakly buffered solutions.\u003C/p\u003E\u003Cp\u003E\u0026nbsp;\u003C/p\u003E\u003Cp\u003E\u003Cstrong\u003E3.
