Erlenmeyer flask - Wikipedia
An Erlenmeyer flask, also known as a conical flask (British English) [1] or a titration flask, is a type of laboratory flask with a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who invented it in 1860.

Acid-Base Titrations - Chemistry LibreTexts
2022年8月30日 · Acid-Base titrations are usually used to find the amount of a known acidic or basic substance through acid base reactions. The analyte (titrand) is the solution with an unknown molarity. The reagent (titrant) is the solution with a known molarity that will react with the analyte.
Titration - Wikipedia
Analysis of soil samples by titration. A typical titration begins with a beaker or Erlenmeyer flask containing a very precise amount of the analyte and a small amount of indicator (such as phenolphthalein) placed underneath a calibrated burette or chemistry pipetting syringe containing the titrant. [18] .
21.17: Titration Experiment - Chemistry LibreTexts
The steps in a titration reaction are outlined below. A measured volume of an acid of unknown concentration is added to an Erlenmeyer flask. Several drops of an indicator are added to the acid and mixed by swirling the flask. A buret is filled with a base solution of known molarity.

2016年7月14日 · With both conical flask and burette filled, you’re ready to start the titration. First, an indicator is commonly added to the conical flask. For acid-alkali titrations, this is a chemical that undergoes a colour change at certain acidities. Two commonly used examples are phenolphthalein and methyl orange.
