TI vs Chemical Solution Wizard

Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun! ONE CAS APP. ALL THE MATH. Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality. Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more. Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.* Visualize crucial connections by observing how equations change — in real time, on one screen — when you touch, grab and interact with shapes, graphs and objects on the screen. Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations. Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board.

Chemical Solution Wizard has been designed to help with preparation and parameterization of complex chemical solutions and derivation of molar weight from chemical formula. Numerous parameters of the complex mixture, such as molarity, molality, mg/ml, solute moles, total volume etc. can be calculated based upon initial data provided, such as: initial molar concentrations of the starting solutions, initial volumes, desired molar ratios and additional solvent volume (dilution). This application targets two main solution preparation tasks: First, "Mixture of Solutions", makes it easy to parameterize complex mixture of several initially provided solutions. And second, "Dissolution", deals with solution formed by dissolution of solid solutes. Layout of "Mixing solutions". Each row represents initial solution, which is going to be mixed to produce a final complex solution. The initial solution parameters to start with are: solute’s molar weight (optional), solute’s molar concentration and volume of the initial solution. Last cell represents molar fraction of the particular solute in the final solution that will be calculated automatically or may be adjusted later on to get the desired components ratio. Bottom row represents final solution parameters: volume of pure solvent that optionally can be added to dilute the solution, Total Molarity and Total solution volume, that can be adjusted at any time, on condition that molar concentrations of the initial solution/s are provided. Layout of "Dissolution". Similarly, each row represents different compound (solid this time) that will be dissolved in the known final volume of the resulting solution. “Solute moles” are the output only cells that will be filled automatically. Final solution parameters row is comprised of absolutely required final solution volume cell and optional final density cell, which may come in handy for calculation of molality. Application features: Unlimited number of components is available. Additional components are added by touching “Solution (+)” field and deleted by touching the top right title field signed with (-). The components list is numbered and scrollable. The application is fully interactive: all parameters are updated instantly after any input that confirmed by pressing "Done" button in the keyboard! (if data is sufficient, otherwise warning will be shown). CSW is now includes molar weight analyser. Pressing of the arrow button in Mw field derives the molar weight of molecular formula in the name field. Examples of supported molecular formula styles: MnSO4.H2O, MnSO4*H2O, (NH4)2CrO4, (NH4)2Fe(SO4)2.6H2O, Ba(C2H3O2)2. In “Mixture”, 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") will be calculated. In "Dissolution", long press on Total Molarity title field will call the menu, where user can choose the options for solution parameters adjustment upon change in total molarity. Please check the molar ratios to ensure that all starting components are included! The application will expel components for which insufficient data is provided! Thus, for example concentration in mg/ml cannot be calculated if Mw of solute is not provided. Similarly, Molality cannot be calculated if final solution density is missing. If user updates molar ratios (percents only), application will not start the calculation until sum of the ratios will be 100 exactly and obviously, not before than initial concentrations (in "Mixing solutions") or Mw (in "Dissolution") are provided. Total Concentration in "mg/ml", Total Moles and Molality fields are for output only. Please confirm input by pressing "Done" or "Enter" button in the keyboard to let application know that data is ready. Application is not sensitive for an unconfirmed input for a good reason. Application assigns dot as a decimal separator.
