How many cations in silver chromate
WebAug 25, 2024 · CaF 2, BaF 2, and PbF 2 are also insoluble. All sulfates are soluble, except those of Ba2 +, Sr2 +, and Pb2 +. The doubly charged sulfates are usually less soluble than halides and nitrates. Most singly charge cations K +, Na +, NH + 4 form soluble salts. However, K 3Co(NO 2) 6 and (NH 4) 3Co(NO 2) 6 are insoluble. Silver chromate is an inorganic compound with formula Ag2CrO4 which appears as distinctively coloured brown-red crystals. The compound is insoluble and its precipitation is indicative of the reaction between soluble chromate and silver precursor salts (commonly potassium/sodium chromate with … See more Silver chromate is usually produced by the salt metathesis reaction of potassium chromate (K2CrO4) and silver nitrate (AgNO3) in purified water – the silver chromate will precipitate out of the aqueous reaction … See more Argentometry The precipitation of the strongly coloured silver chromate is used to indicate the endpoint in the titration of chloride with silver nitrate in … See more Crystal structure The compound is polymorphic and can exhibit two crystal structures depending on temperature: See more • Haynes, William M., ed.
