Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawaban:

wasp stings are alkaline but bee stings are acidic. So if you get stung you need to put bicarbonate of soda on a bee sting and vinegar on a wasp sting.

the pH of bee venom is 5.0-5.5, but the acidity of the venom is not what makes the sting hurt, so adding alkali won't kill the pain (unlike ant stings, which hurt because they're formic acid). ... bees and wasps do have both acid glands and alkaline glands from which they secrete venom

The pH of the lotion was found to be in range of 6-7 which is good for skin pH.
