Easily compute the amount of solid reagent needed to prepare n number of solutions at a specific volume, V, and concentration intervals, ∆C, up to a maximum concentration level, Cmax, where Cmax > ∆C > 0.
An undiluted reagent solution is typically prepared by dissolving an amount of solid reagent in a solvent, usually water. Additional solvent is then added to bring the solution up to a specific volume. With the reagent formula weight the solution concentration can be expressed in moles per liter, after proper unit conversions. A set of undiluted solutions at specific concentration intervals can be prepared in this way, but the calculations can be tedious. This tool was developed to simplify all these calculations.
The tool computes the amount of solid reagent needed to prepare n number of undiluted solutions at specific concentration intervals, ∆C, and up to a maximum concentration level, Cmax, and volume, V, where Cmax > ∆C > 0.
If you wish to prepare a set of reagent solutions by dilution, you may want to try our Diluted Solutions Maker tool instead.
The tool first checks that Cmax > ∆C > 0. If this is the case, the tool then computes the total number of solutions to be prepared and their concentrations. This is done by iteratively subtracting concentration increments.
The amount of reagent needed in each case is computed by multiplying each concentration value by the input volume and formula weights followed by proper unit conversions.
Describe how you would prepare a 500 mL aqueous solution of approximately 0.20 M NaOH from solid NaOH and then a set of less concentrated undiluted solutions in 0.13 concentration intervals.
An aqueous solution is prepared by dissolving 68.99 grams of sodium phosphate monohydrated into a 1000 mL volumetric flask and bringing the volume up to the flask mark. How many less concentrated solutions can be prepared in this way in 0.07 concentration increments?
In the previous exercise: How many moles of reagent per solution were used? How many grams and moles of reagent were used?
