reaction

First, measure out the necessary reagents.

Write down the quantities in your lab notebook.

aldehyde

A test tube inside a beaker on a balance. The tube has a yellow liquid inside, and the balance reads 0.201 g

ethanol

sodium hydroxide

Then add the ethanol and NaOH to the aldehyde, stirring after each addition.

This video shows a small test tube with a faint yellow liquid. A colorless liquid is added and the mixture stirred with a metal spatula. Then another colorless liquid is added and the mixture becomes yellow orange in color, and is stirred with a metal spatula.

Let's add the acetone!
