The tetrazolium salts have the formula ##STR1## in which R.sup.1 is a hydrogen atom, a carboxyl group or an alkyl, phenyl, nitrophenyl, dinitrophenyl, carboxyl-substituted phenyl or trialkylammoniumphenyl radical, R.sup.2 is a phenyl, nitrophenyl, biphenylyl or naphthyl radical, R.sup.3 is a phenyl, carboxyl-substituted phenyl, carboxyl-substituted hydroxyphenyl or dimethylthiazolyl radical, and A.sup..crclbar. is a monovalent anion. The formazanes formed by reaction with reducing substances do not absorb light at all, or absorb light only to a negligible extent, at the measurement wavelength of the redox reaction.New compounds included within the structural formula are those in which R.sup.1 is carboxy, phenyl, 2-carboxyphenyl, 4-carboxyphenyl, 2,4-dinitrophenyl or 4-trimethylammoniumphenyl, R.sup.2 is phenyl, and R.sup.3 is phenyl or 2-carboxyphenyl; with the proviso that, when R.sup.3 is unsubstituted phenyl or 2-carboxyphenyl, R.sup.1 may not be unsubstituted phenyl.
