title: Sulpholane as colour-enhancing and stabilizing agent for silicomolybdic acid.
abstract: Addition of between 20 and 40% v/v sulpholane gives a colour enhancement of silicomolybdic acid better than that achieved with acetone. The beta-silicomolybdic acid is stabilized, and solutions yielding a pH-meter reading of 0>d1-1>d8 give the best results. The photometric measurement is made at about 400 nm. Another advantage of sulpholane is its much lower volatility.
