The Interaction of Aqueous Be(NO3)2 Solutions With Some Organic Acids

Description: 1. A study was made of the interaction between beryllium ions (Be(NO3)2) and oxalic, malonic, succinic, lactic, citric, maleic, and salicylic acids by determining the H+ ion concentration. It was established that the degree of interaction between Be2+ ions and organic acids can be arranged in the following series: oxalate = malonate > salicylate > maleate + citrate > tartrate > succinate > lactate. 2. The inability of the Be2+ ion to form only slightly disassociated compounds in the reaction wi… more

Transistor Counting-Rate Meter

Description: The use of transistors in counting-rate meters has so far been restricted mainly to portable health and survey type monitors. This report points out that transistors may be used successfully in rate-meters of high accuracy and gives examples of practical circuits which may be designed to attain accuracies and linearities of better than +- 1%.

Determination of the Formation Constant of Indiumacetylacetonate by an Extraction Method

Description: 1. The solubility of acetylacetone has been determined in an acetate buffer solution of ionic strength C.1 in relation to pH and temperature. 2. The distribution coefficients of acetylacetone have been determined between chloroform, carbon tetrachloride, benzene and an acetate buffer solution in relation to acetylacetone concentration and pH. 3. The relationship has been established between the rate at which indium acetylacetonate reaches partition equilibrium and the pH, initial acetylacetone … more
