    Chemical Profile and Properties
    This crystalline solid is odorless and appears as colorless, transparent monoclinic crystals. With a molar mass of 248.18 g/mol, it is highly soluble in water and exhibits a cooling effect as it dissolves. A key characteristic is its potent reducing ability, allowing it to easily interact with halogens and heavy metals. However, it is important to note its instability in acidic environments, where it decomposes into sulfur and sulfur dioxide. [1, 2, 3]
    Key Applications
    • Photography: Historically and presently, it acts as a primary fixing agent, dissolving unexposed silver halides to stabilize photographic images.
    • Medicine: It is listed on the World Health Organization's List of Essential Medicines. It acts as an antidote for cyanide poisoning and is used to reduce the risk of ototoxicity in children undergoing certain types of chemotherapy.
    • Water Treatment: It is highly effective at neutralizing chlorine in tap water and swimming pools, converting toxic chlorine gas into harmless chloride.
    • Aquaculture: Frequently used by aquarium enthusiasts and fish farmers to remove chloramines and detoxify copper.
    Safety and Storage
    Sodium thiosulfate pentahydrate is generally considered safe but should be handled with standard laboratory precautions, including gloves and eye protection. It is prone to efflorescence (losing its water of crystallization) when exposed to dry air above 33° C. Therefore, it must be stored in a tightly sealed container in a cool, dry, and well-ventilated area. [1]
