Conductivity and density of chromic acid solutions

The conductivity and density of chromic acid solutions were determined (<*r concentrations up to 10 molar (1,000 g/1 of Cr03 ). The density is practically a linear function of concentration. The conductivity increases to a maximum at about 5 molar and then decreases. CONTENTS Page

Chromic Acid Oxidation of Lactic Acid Catalysed by Manganese(II)

B ak o re and N a r a in 1 studied the kinetics of the oxidation of a-hydroxy acids by chromium(VI) and found that addition of Mn(II) decreases the rate of oxidation to one half of that in absence of Mn(II), when the hydrogen ion concentration is in the range 0.1 to 0.4 M. They attributed this to the disproportionation of Cr(IV) by Mn(II) ions. K em p and W a t e r s 2 observed Mn(II) catalysis...

New Grocott Stain without Using Chromic Acid

We established a new "ecological" Grocott stain for demonstrating fungi, based upon a 4R principle of refusal, reduction, reuse, and recycle of waste management. Conventional Grocott stain employs environmentally harsh 5% chromic acid for oxidization. Initially, we succeeded in reducing the concentration of chromic acid from 5% to 1% by incubating the solution at 60°C and using five-fold dilute...

On Hæmorrhagic Lupus of the Female Genital Organs

I narrate these cases merely as rare experience in practice, wishing, meantime, to avoid discussion of the nature of the disease. In accordance with general practice I designate it lupus, yet histological investigation by skilled colleagues shows that it has not the structural peculiarities of most examples of the characteristic and well-known disease in other parts of the body. The name of lup...
