The invention relates to a novel process of joint production of sodium carbonate and hydrochloric acid (or hydrogen chloride), belonging to the field of basic chemical industry. The invention solves the problems existing in the sodium carbonate industry and chlor-alkali industry in China at present...

6 A solution mixture contains both sodium carbonate (M_r=106) and sodium hydrogen carbonate (M =84.0).25.0 cm3 of the solution mixture was titrated against 0.300 mol dm-3 hydrochloric acid.15.0 cm3 of HC/ is required to decolourise the phenolphthalein indicator. A few drops of methyl ...
Sodium carbonate has environmental applications as well. It can be used to treat and improve the alkalinity of lakes that have been affected by acid rain. And because it reacts with sulfur dioxide and hydrochloric acid, soda ash can help to purify the air coming out of chemical stacks and ...
A bottle of 50% NaOH will have sodium carbonate on the bottom and on the sides. Therefore, the 50% NaOH must be removed from the middle of the bottle avoiding the sides of the bottle and the bottom. The bottom third of the bottle should never be used for eluent preparation and the ...
Sodium carbonate is endothermic when dissolved in water, and it is easy to weather in the air. Na2CO3 · 7H2O is unstable and can only be precipitated from sodium carbonate saturated solution in the range of 32.5~36 ℃. Sodium carbonate is a weak acid and strong alkali salt (soda ash is...
The amount of sodium hydrogencarbonate or hydroxide (in mmol h−1) required to keep the pH at 5.5 is equal to the rate of postprandial gastric acid secretion. The method is reproducible and is the simplest of the methods used to measure meal-stimulated gastric acid secretion. A major ...
