Question

1) For the Greener Bromination of Stilbene Laboratory, you use an analytical balance to obtain the mass of your solid starting material on a tared piece of pre-folded weighing paper. You obtain a mass of 0.5012 g. Which of the following should you do? Select all that apply

Dispose of the solid starting material and start again. You need exactly 0.5000 g.

Recalculate your theoretical yield.

Record the actual amount you use in your lab notebook.

Transfer the solid to a clean, dry beaker. Then use a spatula to transfer the solid to the reaction vessel.

Explanation / Answer

For greener bromination we need to transfer the solid to a clean, dry beaker. Then use a spatula to transfer the solid to the reaction vessel, as by doung so we can minimize the loss of the chemical.
