    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.
