Now why would you put baking soda on that..
Well I remember our teacher telling us about putting a basic substance on a bee sting because it's acidic.......but I don't really remember why
I'm really impressed..what you did was rightbutyou mjst firstknow what exactly occurs.What was supposed to happen was a neutralization reaction. It's the reaction between an acid and base that nullifies each other's effect resulting in a change to pH closer to neutral. By putting an alkaline you had to increase the pH to restore your skin to normal.
Supposed to? What do you mean?

Oh haha that well is because that was not a bee sting...it was a wasp sting
Now this is a tough situation when you can identify the insect..Unlike bees ,wasp stings are ctually alkaline so..
Exactly! Now that you've understood let's go rinse your hands and gently apply some diluted vinegar .

We just found its nest in the garage during the spring clean up.
Amy's mom tells her to calm down and Amy narrates the incident...
...so when I put baking soda it worsened my condition, increasing the pH instead of decreasing it.
