sodium chloride is water-soluble. calcium carbonate isnt. both compounds can be seperated by dissolution (Addition of excess of water), follow by filtration. calcium carbonate is obtained as the residue whereas sodium chloride solution is the filtrate. heat the filtrate to dryness to recover the ...
In the first step the resin is submitted either to a carbonic dioxide bubbling or to an acid treatment in order to remove the calcium carbonate from the resin; the second step employs a sodium chloride solution and the thirth one a sodium carbonate solution. By this process sugar colourants ...

000 solution. Potassium permanganate tablets can also be used. If using 400 mg tablets,add one to each 4 L of water. The tablets should be dissolved in hot water before pouring into the bath.
Dried grapes are stored at three levels of temperature (4°, 18° and 32°C) with three relative humidity. Relative humidity gets from saturated solution of potassium carbonate salt, potassium acetate and sodium chloride salt. We assess the color of samples in (2, 5 and 8 months) by Hant...

After heating on a water bath, 2-4 drops of a freshly prepared 10 per cent solution of dry aluminium chloride (sublimed, "pro synthesi") in absolute alcohol are added and the heating is continued. If vitamin D is present, a deep violet colour appears at the bottom of the test-tube, ...
°C and 36 °C for 30 min with a 150 µL substrate solution (0.1 M sodium phosphate buffer pH = 8.4; 1.7 mM NADH; 0.25 mM NADPH; 0.2% (v/v) Triton-X-100) and 50 µL reagent solution (2.5 mM 2-(p-iodophenyl)-3-(nitrophenyl)-5-phenyl tetrazolium chloride (INT) solution)....
A race to find the best strains to solve azo dye pollution ended up manifesting more problems rather than providing a good solution. This dilemma has been going on for the past few decades, leading to various methods and media used for the purpose of isolation. However, the role of method...
