Regularly Asked Questions (FAQ) 1. What is the difference between an endpoint and an equivalence point? The equivalence point is the theoretical point in a titration where the quantity of titrant included is chemically comparable to the amount of analyte in the sample. The endpoint is the physical point where a modification is in fact observed (such as a color modification or a voltage spike). Professional titration services utilize automated sensing units to make sure the endpoint is as near the equivalence point as possible.
2. Why is Karl Fischer titration so common? Karl Fischer titration is distinct since it is highly particular to water. Unlike other techniques that might measure all volatile substances, Karl Fischer only reacts with water, making it the market requirement for moisture analysis in a variety of materials from liquids to solids.
