What is an Erlenmeyer flask and what does it do?
The Erlenmeyer filter flask, which is also known as a conical flask was named after Richard August Carl Emil Erlenmeyer. It consists of a wide base with a flat bottom and an inverted cylindrical neck. It’s usually used in chemistry experiments in order to mix different chemicals or to contain titrate of a solution.
What is the function of the flask?
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
What is an Erlenmeyer flask not used for?
Glassware – Flasks. Erlenmeyer flasks and beakers are used for mixing, transporting, reacting, and filtration but not for accurate measurements. The volumes stamped on the sides are approximate and accurate to within about 5%. Beakers are used to contain volumes of liquids.
Is flask a frontend or backend?
Flask is used for the backend, but it makes use of a templating language called Jinja2 which is used to create HTML, XML or other markup formats that are returned to the user via an HTTP request.
Is a beaker more accurate than a conical flask?
Volumetric Glassware Graduated cylinders, beakers, volumetric pipets, burets and volumetric flasks are five kinds of glassware often used to measure out specific volumes. Volumetric pipets, flasks and burets are the most accurate; the glassware makers calibrate these to a high level of accuracy.
Why titration flask should not be rinsed?
The second and more important reason for rinsing your burette has to do with water. Consequently, if you don’t rinse your burette with titrant and there really is some water remaining inside, the titrant you dispense will be more dilute than it should be.
Is Flask good for front-end?
Flask comes with a small set of easy to learn API, and the documentation is excellent. If you are new to Python, start your web development with Flask, so that you can get the feel of backend and frontend both as well as learn the core concepts well.
Is Python front-end?
Python: Is Python front end or back end? The simple answer is yes: Python can be used for either front-end or back-end development. That said, it’s approachable syntax and widespread server-side use makes Python a core programming language for back-end development.
What happens if conical flask is rinsed with water?
It reduces the chance of solution splashing out whilst swirling. During a titration, a chemist rinsed the inside of the conical flask with deionised water. The water used for rinsing remained in the conical flask. Water isn’t an acid or an alkali so won’t change the number of moles needed in the flask.
