How many grams of precipitate will be formed in a reaction of 1.0 M sodium carbonate (20.0 mL) and 1.0 M calcium chloride (20.0 mL)? What theoretical yield of NaCl in grams would result from reacting 5.00 mol of Na2CO3 with excess HCl?
Sodium iodide is a white solid obtained through the reaction between sodium carbonate with hydroiodic acid and further evaporation of the solution. There are anhydrous, dihydrate and pentahydrate compound. It is the raw material for the manufacturing of iodine, for being used in medicine and photogr...
In the wash process, sodium percarbonate does form hydrogen peroxide and sodium carbonate. Sodium carbonate is a water-soluble mineral and ubiquitously present in the aqueous environment as there is an equilibrium with carbon dioxide from the atmosphere and with other dissolved minerai carbonates. ...
