Titrationis an analytical chemistry technique used to find an unknown concentration of an analyte (the titrand) by reacting it with a known volume and concentration of a standard solution (called thetitrant). Titrations are typically used foracid-base reactionsand redox reactions. Here's an examp...

Weak Acids and Strong Bases ThoughtCo / Todd Helmenstine A weak acid only partially dissociates from its salt. The pH will rise normally at first, but as it reaches a zone where the solution seems to be buffered, the slope levels out. After this zone, the pH rises sharply through its e...
+, and the bases, HSO4–and H2O. The Brønsted concept offers a precise criterion for relating chemical reactions to the acid-base type. It makes it possible to express the basic characteristics of protolytic equilibriums in quantitative form and to arrange hydrogen-containing substances in a ...

Did you know that some juices and vinegar taste sour because of the chemical properties of the acid in those liquids? And that when acids and bases are mixed together, they always counteract each other, producing water and a salt? Terms you should know hydroxide ion a negatively charged ch...
Titrations Buffers Although I've told you that acids and bases aren't hard to understand, I've got bad news: There are not one but three common definitions used to describe acids and bases: Arrhenius acids and bases, Brnsted-Lowry acids and bases, and Lewis acids and bases. Though this...
