GPrepared by melt are dissolved in a solvent to dissolve the preparation by this method is the preparation of new aqueous solution by the dance was pure substances which are dissolved in the melt in the solvent (water). Mol/dm3 with procedures to prepare as follows:
. 1. calculate the quantity of the substance (g) As to the substance, weighing 2.
which is calculated in accordance with article 1 (if solid), but if it is a liquid volume measuring methods may be used (using substances weighing scales!)
3.Bring substances weighing bottle holders has been measured at constant volume (Volumetric flask), which is equal to the volume of solution needed to fill distilled water in amounts enough to dissolve all substances out of solution, shake
4.Fill distilled water into a measuring container volume until the volume of stripping capabilities. Close the stopper, shake to mix into a single body, aqueous solution with the intensity and volume as required
.Prepare a solution by taking the original solution diluted down to prepare a solution by solution greater concentration, the original solution to prepare the dilution water fill up with concentration. 1. calculation of the volume of old solution that uses
2.Use Pi pet or measuring a volume equal to the volume of a substance dissolved in an aqueous solution 1 same suction and discharge volume of bottle holders, which has a capacity equal to the volume of a solution it will want to
.Preparation of aqueous solution by aqueous solution with different concentrations combination. Measuring the volume of bottles will still need the volume absorbing solution, using pet, PI
