Reaction of bee sting acids with medicated cream

Bee Sting Acids

Medicated Cream

Sodium hydroxide is an ingredient found in many medicated creams. It is a white powder that is used as a pH adjuster. The chemical formula for sodium hydroxide is NaOH.

Balanced Chemical Equation

Type of Reaction

Formic acid is acidic, meaning that in order to get rid of it's acidic properties it must be neutralized. The sodium hydroxide in the medicated cream is used as a base to neutralize the formic acid, making this type of reaction neutralization. This reaction could also be classified as double displacement.

Use in Everday Life

This chemical reaction is very important in the use of everday life. Everday, many people are stung by bees and have to deal with the pain and discomfort of the formic acid in their skin. Some people may also suffer from an allergic reaction that could be life-threatening. By applying a medicated cream, this diminishes the pain and allows them to continue on with their day without any worries.

The acid found in bee stings is known as formic acid. Formic acid is a colourless solution with a pungent odour. The chemical formula for formic acid is HCOOH.

HCOOH (aq) + NaOH (aq) --> HCOONa (aq) + H2O (l)

The Buzz on Bee Stings

In the video above, a student allows a bee to sting them for an experiment. You can see that after the stinger leaves the bee, it still continues to pump formic acid into the skin, displaying the size of the dose. Although it is not shown, the formic acid would then irritate the skin, which is why it is so important to use medicated creams to neutralize the bee sting's acidic properties in order to bring the irritation down.
