Study Notes
Mercury and Its Reagents
- Mayer’s reagent functions as an antiseptic component.
- Erethism occurs due to mercury vapor exposure, leading to mood changes, irritability, and social difficulties.
- Severe cases of erethism can involve delirium and memory loss.
- Common antidotes for mercury poisoning include EDTA and sodium formaldehyde sulfoxylate.
- Albumin can induce emesis in emergency cases using egg white (one egg white for 250 mg of mercury).
- Mercury compounds include:
- Hg2Cl2 (Mercurous chloride) known as Calomel, which is a cathartic.
- HgNH2Cl (Ammoniated Mercury), recognized as a topical anti-infective.
Cyanide Poisoning
- Cyanide poisoning can be treated with:
- Sodium nitrite (NaNO2) and amyl nitrite.
- Sodium thiosulfate, acting as an antidote by converting cyanide to thiocyanate.
- Methylene blue and hydroxocobalamin serve as additional treatment options.
- Sodium thiosulfate is also known as "hypo," originally from hyposulphite of soda, used in photographic processing.
(3A) Boron Family
- Members of the Boron family are chemically reactive.
- Sodium thiosulfate (Na2S2O3) is known for its role in various clinical applications and as an antidote for cyanide poisoning.
Ammonium Compounds
- Ammonium ions (NH4⁺) result from the protonation of ammonia (NH3).
- Ammonium iodide (NH4I) acts as a source of iodine and can serve as an expectorant and antifungal.
- Ammonium acetate (NH4CH3COO) is noted as Spirit of Mindererus, a styptic agent.
- Household ammonia solutions are used as circulatory stimulants and counterirritants.
Additional Chemical Properties
- Cesium is a catalyst in resin formation and derives its name from the Latin for "sky blue," due to the blue color of its salts when heated.
- Nessler's reagent, composed of potassium iodide, mercuric chloride, and potassium hydroxide, is utilized for ammonia detection.
