Step-by-step explanation:
The Erlenmeyer flask got its name from the German chemist Emil Erlenmeyer, who designed it in 1860. This piece of laboratory glassware has a conical base with a cylindrical neck and is commonly used for swirling liquid solutions without risk of spillage due to its sloping sides. It is versatile, allowing for the mixing of solutions, conducting of chemical reactions, and can even be used when performing titrations, as it assists in mixing the reagents thoroughly.
