You have been assigned a drawer filled with the glassware that you will be using while performing experiments. Check each action that should be performed prior to beginning your experiment.

Answer: Check what kind of glassware is required in the experiment. then check the glassware is correctly washed and with neutral pH.

Explanation: Any time we run an experiment, we must check out what kind of process we will do, like boiling, freezing, among others in order to check if the glassware available is the correct one.

Pyrex Material: Usually any process in the laboratory is mandatory to use pyrex glassware that is made of borosilicate glass, this material will handle changes in any temperature; it is also highly resistant to chemical attack and can be used with most acids, alkalis and organic solvents. Clean and dry glassware : It's important to have all the glassware clean and dry. Any dust or dirt can interfere in your experiment, leading you to wrong results. Neutral pH: It is mandatory to wash all glassware witn neutral pH soap this is important because usually all industrial soaps will leave alkaline residue that will alter your experiment too.
