Reaction Steps
A solution of 0.78 g of sodium carbonate and 2.55 g of sulfanilic acid in 55 ml of water was cooled to 0° C., and 6 ml of an aqueous solution containing 1.11 g of sodium nitrite was added. Further, 15 ml of cold 2N-HCl was added while maintaining the temperature in the range of 0° to 5° C., to form p-sulfophenyldiazonium chloride. Starch iodide paper was used in recognizing the end of reaction.
