View Solution Aqueous solution of sodium succinate on electrolysis gives mainly View Solution Aqueous sodium hydroxide using graphite electrode View Solution Write balanced equations for the following reactions : (i) Iodine with hot conc. sodiu...
disodium carbonate. Then wash away with plenty of water. 4.4 DisposalMethods SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its ...
Citric acid is used in food and beverage industries as flavoring and preservative and in pharmaceuticals to maintain and adjust the pH of the formulations. It is used in dietary supplements, cosmetics, and as a cleaning and chelating agent. ...
Oxidation of the aldehyde 12n-Et (Figure 5) and subsequent esterification of the free carboxylic acid with dimethylcarbonate and diaza(1,3)bicycle[5.4.0]undecane (DBU) furnished model compounds in 21% yield over two steps. Sign in to download full-size image Figure 5. Molecular structure of...
Whereas, when zinc carbonate is dissolved in dilute nitric acid and then ammonium hydroxide is added to it. A white precipitate is formed which is soluble in excess of ammonium hydroxide. 14. What is observed when hot concentrated caustic soda solution is added to (a) ...
Then, a 10% sodium carbonate solution (300 µL) was added to the reaction and the solution was incubated at room temperature for 30 min. Optical density was determined at 750 nm using a VERSA max microplate reader (Molecular Device, San Jose, CA, USA). Results were calculated in mg ...
