Chemical Solution Wizard

About Chemical Solution Wizard Android App

This application helps to prepare and fully parameterize various chemical solutions, starting from simple dilution and up to mixture of infinite number of independent components and pure solvent.

App requires internal storage access permission in order to store database.

This app is part of Chemistry Lab Pack including 9 apps dealing with chemical solutions, reaction equilibrium, solubility, precipitation, acid base neutralisation reaction, titration, chemical kinetics and liposome preparation.

First activity, "Mixing solutions", makes it easy to parameterize complex mixture of several initially provided solutions.

Second activity, "Dissolution", deals with complex solution formed by dissolution of multiple solid solutes.

Furthermore, it allows calculation of various parameters, such as concentration (molarity, molality and mg/ml), solute moles and molar ratios upon mixing and dilution of ready solutions and upon dissolution of multiple solid solutes.

Application includes fully customizable database for storing molecular weights of the frequently used compounds. The stored data will be available to autocomplete the typed solute names and automatically provide Mw.

This application is fully interactive: all system parameters (including final) can be adjusted to meet the needs. For example: final molar concentration, total solution volume and molar ratios of the components can be adjusted at any time to get needed volumes of initial solutions or masses of solutes that have to be taken in order to prepare the final solution.

Additional application features.

•Unlimited number of components is available. Additional components are added by touching “Components (+)” field and deleted by touching the bottom left title field signed with (-). The component list is numbered and scrollable. Please pay attention to unused components containing data, that may disturb with calculations!

•The app is including Molar Mass Analyser. Press on arrow in the Mw field initiates analysis of chemical formula in the component field and set the value to Mw field. No charge values should be used. Valid examples: Mg(HCO3)2, CaCl2.2H2O, CaCl2*2H2O, (NH4)2Fe(SO4)2.6H2O, Mg(H2PO4)2, C6H12O6. Analyser is case sensitive.

•Application includes database for storing molecular weights of the frequently used compounds. The database can be stored and restored to and from phone storage, so practically, it can be edited and uploaded externally (while preserving the name and structure). Upon database restoring, system automatically backs up the current version, so it can be restored at any time. The stored database files can be found on phone memory in folder “Chemical Solution Wizard”.

•Upon typing of solute names into component cells the software will suggest to autocomplete with stored information from the database.

•The application is fully interactive: all system parameters are updated immediately after any input from user (if it is sufficient, otherwise warning will be shown).

•If molecular weights (Mw, units "g/mole") of solutes are provided as well, then concentrations in units of grams of solute per litre of solution ("g/l" equivalent to "mg/ml") can be calculated.

•In "Dissolution" activity, long press on Total Molarity cell will call the menu, where user can choose the options for solution parameters adjustment upon change in total molarity.
