How many cations in silver chromate
WebTin (IV) chromate is the name for the compound with the formula Sn (CrO4)2. With two chromate ions, each with a 2- charge, the charge on tin must be 4+ to balance the charges between the cation and anion. Tin cations can have a 2+ or 4+ charge, so a roman numeral must be included in the name.
