#TryThisTuesday: Make your own Sherbet

sherbet

This week we’re taking on the science of sweets! Here is a super easy way to make your own sherbet powder at home.

All you will need is:

  • 7 teaspoons of sugar (either caster sugar or icing sugar)
  • 1 teaspoon of bicarbonate of soda
  • 3 teaspoons of citric acid in powder form

Mix your ingredients in a bowl and then take a small amount on a teaspoon and have a taste. It should fizz in your mouth.

Where does the fizz come from?

When you place the mixture on your tongue it reacts with the water in your mouth and produces carbon dioxide, this causes the fizzy feeling.

The reaction occurs because  acids, like the citric acid used here, release charged hydrogen particles when added to water. These particles will attack an alkaline (the opposite of an acid) such as bicarbonate of soda. The reaction produces more stable molecules Рwater and carbon dioxide.

If you pour water onto your mixture you should be able to see the reaction that’s happening in your mouth. You can actually feel the carbon dioxide gas being released if you hold your hand close to the surface.
