Formic acid, which is a component of insect venom, has a ka = 1. 8 ✕ 10-4. what is the [h3o ] in a solution that is initially 0.
1 answer:
The [H3O+ ] in a solution that is initially 0. 10 m formic acid, hcooh is 0.00415M.
<h3>What is formic acid? </h3>Formic acid is defined as the simplest carboxalic acid which contain one carbon atom. It is weak acid.
- Another name of formic acid is methanoic acid.
- It is used as the preservation and antibacterial agent in livestock feed.
- Exposure to Formic Acid can cause headache, dizziness, nausea and vomiting. individuals, may cause a skin allergy.
Thus we concluded from the image that the
concentration of [H30+] is 0.00413M.
