TL;DR: In this article, a linear relation between the quantity of material and the light absorption is not generally observed in heterometry, and no protective colloids are used in Heterometry.

TL;DR: In this paper, the reaction between cobaltous or cobaltic and α-nitroso-β-naphthol was extensively studied heterometrically both in water and in alcoholic solutions.

TL;DR: In this article, a heterometric method is presented for the determination of cobalt in solutions or other metals, which comprises 0.1-3% of the total metal content.

TL;DR: In this paper, a heterometric titration with α-nitroso-β-naphthol is performed to determine the amount of iron in a solution of 50% alcoholic solution.

TL;DR: In this paper, a general method was presented for the determination of 1 -2 mg mercuric mercury, in the absence of complexing agents, in 20 ml solution, with an error of 0 -3 %.

TL;DR: In this paper, the authors used dilute alcoholic or a dilute aqueous solution for the determination of murcury or mercaptobentlnazole in 20-30 ml with an error of 0-3% and 10-20 min.

TL;DR: In this article, the initial precipitation of copper-salicylaldoxime occurs at pH~1.5 and 3.0, and a complete precipitation occurs in the pH-region of 3-10.1 and 10.7.
