Match List I with List II LIST-I Complex LIST-II Colour A. Mg NH 4 PO 4 I. brown B. K 3 Co NO 2 6 II. white C. MnO OH 2 III. yellow D. Fe 4 Fe CN 6 3 IV. blue Choose the correct answer from the options given below:

TestHub · Accepted Answer

The formula Mg ( NH 4 ) PO 4 represents magnesium ammonium phosphate it is white in colour. K 3 Co NO 2 6 is known as potassium hexanitritocobaltate(III). It is yellow in colour. The yellow colour is due to the presence of the cobalt ion (Co3+) in the complex, which absorbs certain wavelengths of light and reflects yellow light. MnO OH 2 is brown in colour. Fe 4 Fe CN 6 3 is blue in colour. Complex Colour Mg NH 4 PO 4 White K 3 Co NO 2 6 Yellow MnO OH 2 Brown Fe 4 Fe CN 6 3 Blue
