Matching the compounds with their typical colours: A. Urea is a white crystalline solid (2). B. Hydrous copper sulphate (CuSO\u2084\u00b75H\u2082O) is commonly known as blue vitriol and has a distinctive blue colour (1). C. Lead sulphide (PbS) is a black solid (4). D. Potassium permanganate (KMnO\u2084) is a dark purple solid that forms intense pinkish-purple solutions (3). The correct match is A-2, B-1, C-4, D-3.<\/section>\n
Many chemical compounds have characteristic colours, which can be used for identification or in analytical chemistry. The colour arises from the absorption and reflection of light due to the electronic structure of the compound, particularly in transition metal compounds like copper sulphate and potassium permanganate, or in some ionic or covalent compounds.<\/section>\n
Anhydrous copper sulphate (CuSO\u2084) is white; the blue colour appears upon hydration. Potassium permanganate is a strong oxidizing agent and its colour changes upon reduction, which is used in titrations.<\/section>\n","protected":false},"excerpt":{"rendered":"
