What is a Barium chloride (BaCl₂)?

Barium chloride (BaCl₂) is an inorganic salt composed of barium and chlorine. It appears as a white powder or colorless crystals and is highly soluble in water, acting as a strong electrolyte in solution. It is commonly used in analytical chemistry to detect sulfate ions, in metal heat treatment baths, pigment production, and as a green colorant in fireworks, utilizing barium's characteristic green flame. Despite its utility, barium chloride is highly toxic, and ingestion can be fatal. Protective gear such as gloves and safety goggles should be used when handling it. It must be stored in tightly sealed containers, away from moisture. Due to its affordability and stability, it is widely used in various industrial applications involving barium compounds.
