perchlorate
Definition
Noun: A perchlorate is a chemical compound that is a salt derived from perchloric acid. It contains the negatively charged ion (anion) ClO₄⁻. Perchlorates are often highly soluble in water and are strong oxidizing agents, meaning they can readily accept electrons from other substances in chemical reactions.
Usage
Perchlorates are primarily discussed in scientific and industrial contexts. * They are used in rocket propellants, explosives, and fireworks due to their oxidizing properties. * Some perchlorate salts, like ammonium perchlorate, are key ingredients in solid rocket fuel. * Perchlorates can also occur as environmental contaminants, sometimes found in soil and groundwater.
Examples
- The laboratory analyzed the water sample for traces of perchlorate.
- Ammonium perchlorate is a common oxidizer in composite propellants.
- The cleanup of perchlorate contamination at the site is a priority.
Advanced Usage
- Perchlorate is often discussed in environmental chemistry and toxicology due to its potential to interfere with thyroid function by competitively inhibiting iodide uptake.
- In analytical chemistry, specific tests exist to detect and quantify perchlorate ions in a solution.
