The application of a linear algebraic method to the potentiometric titration of a mixture of tartaric and citric acids and sodium carbonate and sodium hydrogen carbonate (previously treated with strong acid), permits the determination of the concentration of each individual acid and the total equivalent of carbonate in antacids. It is also possible to determine individual concentrations of sodi...

The rate of decomposition of hydrogen peroxide has been measured in aqueous, concentrated (0.1–1M) reagent-grade sodium carbonate liquors and compared with that in sodium hydroxide liquors at the same pH, temperature, and ionic strength. Over the ranges of temperature (303–323 K), pH (10.0–10.6), and ionic strength (1.5–3.0M), and without peroxide-stabilizing additives, hydrogen peroxide decomp...

The effects of raw and sodium hydrogen carbonate-treated oak acorn were evaluated on broiler chicken performance and cecal flora. A total of 340 one-day-old broiler chicks were used in a completely randomized design with five experimental treatments and four replicates with 17 birds each. A corn-based diet served as the control and four treatment groups were diets containing 20 or 25% raw or tr...

Dehydration of N -formamides to isocyanides using p -toluen sulphonyl chloride, sodium hydrogen carbonate in aqueous micelles is reported.

Organic matter removal is accomplished rapidly and efficiently without removing carbonates by treating samples wi~h a sodium hypochlorite solution. Quantities of organic matter lefr in samples by this treatment are commonly less than remain after hydrogen peroxide treatment of acidified samples. Stable suspensions result from the use of a sodium carbonate-sodium bicarbonate solution to wash and...

An electrochemical cell comprising a novel dual-component graphite and Earth-crust abundant metal anode, a hydrogen producing cathode and an aqueous sodium chloride electrolyte was constructed and used for carbon dioxide mineralisation. Under an atmosphere of 5 % carbon dioxide in nitrogen, the cell exhibited both capacitive and oxidative electrochemistry at the anode. The graphite acted as a s...
