Here's why:
* The venom: Jellyfish stings contain nematocysts, tiny capsules filled with venom. This venom is a complex mixture of proteins and enzymes, designed to paralyze prey and defend the jellyfish.
* pH doesn't matter: The pH of the venom doesn't play a significant role in its effectiveness. It's the specific toxins within the venom that cause the pain, swelling, and other symptoms.
* Acid/alkaline are irrelevant: While some household remedies like vinegar can be used to neutralize certain types of jellyfish stings, this doesn't mean the sting itself was acidic or alkaline. Vinegar works by altering the environment around the nematocysts, preventing them from releasing more venom.
In short, jellyfish stings are toxic, not acidic or alkaline.
