Next‚ right click on the flask and select Buchner Funnel. Right click on the beaker and select Pour/Decant. Move the beaker above the funnel and you will see a white area at the bottom of the flask. 4. Lastly‚ you will need to record the weight of the precipitate. Right click on the flask and select Buchner Funnel. A message

Erlenmeyer flask Analytical balance (+0.0001g) A clean 250 ml beaker was filled with 200ml of DI water and put aside to equilibrate to room temperature. Temperature was taken with a thermometer. A 50 ml Erlenmeyer flask was then cleaned rinsed and removed from water. The flask was marked with a pen and placed in oven to dry‚ then placed in desiccator to cool. The 10 ml volumetric pipet was cleaned with hot soapy water and rinsed with DI water before use. The mass of the empty flask with stopper

Jesse‚ Science: Bunsen Burner guide ______________________________________________________________________________ Have you ever wanted to try out a Bunsen Burner? If yes‚ then this is the guide for YOU! Before we get to the Bunsen burner‚ you need to know some important stuff: SAFETY. Safety is very important‚ because once you do not obey the rules‚ you can be in big‚ big trouble. So let me tell you the safety rules: 1. always wear a lab coat/lab goggles when doing a experiment

round bottomed flask‚ Hirsch funnel and filter flask. PROCEDURE: 1. Take a 50-mL round-bottomed flask and a small condenser and set up a reflux apparatus. Arrange a ceramic fibre-centered wire gauze on an iron ring such that it remains two inches above the burner. Position the clamps on flask and condenser accordingly. 2. Weigh a 2.0-g of impure acetanilide and keep just pinch of it aside for melting point determination. Add rest of it to the 50-mL flask by temporarily

(QF) round bottomed flask in the fume cupboard as 4 – aminophenol is toxic. Ethanoic anhydride (toxic vapor) was added and mixed by swirling and a reflux condenser was attached and fixed onto a clamp stand and heated for ten minutes on a steam bath with occasional swirling. The mixture was cooled at room temperature and further cooled with cold tap water. The crude solid that formed at the bottom of the condenser was vacuum filtered and transferred into a conical 100cm3 flask. A hot plate was used
