CALCULATOR PARTS

2.1. Main Window

The main window consists of three parts: the Target area at the top, the Source area in the middle, and the Result area at the bottom.

Target area

• In the "Desired solution" field put in the formula of the chemical you are currently making.
• Click the Show Database button to show the Database of common compounds window.
• In the "Final volume" field add the volume of the solution you are currently preparing and choose a unit of measurement for the volume.
• In the "Desired concentration" field type the concentration of the solution you are making and chose a unit in which the concentration is expressed.

Source area

The Source area is divided into two parts, each of which represents the composition of one component that is used to create our solution. We can dissolve solid salt in water, dilute a concentrated solution or from two solutions (one that has a higher and one that has a lower concentration than wanted) create a solution with the desired concentration.

If the "Solid" option is selected the number under the chemical's formula indicates its purity ("Purity of solid compound") and if the "Solution 1" option is selected the number indicates its concentration ("Concentration of first solution").

• Clicking on the name of the compound you can choose a new name from the list or write your own in.
• If the salt, from which the desired solution is being made, is a hydrate it is necessary to add the number of water molecules after formula of the source chemical.
• In the "Concentration of first solution" field type the concentration of the solution you are making and chose a unit in which the concentration is expressed. If the "Solid" option is selected the number under the chemical's formula indicates its purity ("Purity of solid compound") and if the "Solution 1" option is selected the number indicates its concentration ("Concentration of first solution").
• The second part of the Source area is reserved for the solvent (usually water). By choosing the Solution 2 option you can prepare a mixture of two solutions of different concentrations or you can increase the concentration of a solution by adding solid salt.

Result area

SolCalc automatically calculates the necessary amount of chemicals as soon as some information changes. By clicking on the Show Lab Report button you will get the complete list of all calculations that were done and recipes for preparation of the desired solution.

• The first field displays the calculated mass of solid compound or the calculated volume of first solution. You can choose a unit in which the mass (volume) is expressed.
• The second field displays the approximate volume of solvent (water) or the calculated volume of second solution. You can choose a unit in which the volume is expressed.
