  2. Karl Fischer titration - Wikipedia

    en.wikipedia.org/wiki/Karl_Fischer_titration

    The glass walls of the vessel adsorb water, and if any water leaks into the cell, the slow release of water into the titration solution can continue for a long time. Therefore, before measurement, it is necessary to carefully dry the vessel and run a 10–30-minute "dry run" in order to calculate the rate of drift.

  3. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  4. 2,2-Dimethoxypropane - Wikipedia

    en.wikipedia.org/wiki/2,2-Dimethoxypropane

    DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2] This property can be used to accurately determine the amount of water in a sample, alternatively to the Karl Fischer method. [3] DMP is specifically used to prepare acetonides: [4] [5]

    en.wikipedia.org/wiki/Glossary_of_winemaking_terms

    Wine packaged in a bag usually made of flexible plastic and protected by a box, usually made of cardboard. The bag is sealed by a simple plastic tap. Brettanomyces A wine spoilage yeast that produces taints in wine commonly described as barnyard or band-aids. Brix/Balling A measurement of the dissolved sucrose level in a wine Brouillis

  6. Wine chemistry - Wikipedia

    en.wikipedia.org/wiki/Wine_chemistry

    Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds.

  7. Hydroxyacetone - Wikipedia

    en.wikipedia.org/wiki/Hydroxyacetone

    It consists of a primary alcohol substituent on acetone. It is an α -hydroxyketone, also called a ketol, and is the simplest hydroxy ketone structure. It is a colorless, distillable liquid.

  8. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acid–base_titration

    Acid–base titration is also utilized in the analysis of acid rain effects on soil and water bodies, contributing to the overall understanding and management of environmental quality. [24] The method's prevision and reliability make it a valuable tool in safeguarding ecosystems and assessing the impact of human activities on natural water ...

  9. Winkler titration - Wikipedia

    en.wikipedia.org/wiki/Winkler_titration

    The Winkler test is used to determine the concentration of dissolved oxygen in water samples. Dissolved oxygen (D.O.) is widely used in water quality studies and routine operation of water reclamation facilities to analyze its level of oxygen saturation .
