Chemical Solution Wizard vs Chemistry AI·

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.

THE PERIODIC TABLE You can find: period, group, atom mass, class, valence, type of crystal lattice, color, temperature of melting and boiling, electronic configuration, energetic levels, electronegativity. PROTECTION FROM TEACHER: Call From Mom and Clock John is cheating on his grand test. The Teacher notices that and tries to take his phone. “Excuse me, my mom is calling”, says John and shows the screen to the Teacher. There is a phone call from John’s mom. “Go to the hall and pick up the phone”, she suggests. In the hall John taps on the lest top corner of the screen – and there is a solved task as before! He remembers the solution and comes back to the classroom. His mom didn’t call him. John has turned on protection from the teacher. There are 2 types of protection in “Chemistry X10” – Call From Mom and Clock. Clock works by default, Call From Mom is available in Pro-version. ----- “Pro-version” is a service upon monthly subscription. It gives you infinite gems and access to features which are available only in “Pro-version”: protection from teacher “Call From Mom” and detailed solution of tasks. “Pro-version” costs 1.99 USD (equivalent in local currency) per week. Subscription will be updated automatically if you don't turn off auto-extension of subscription 24 hours before current subscription expiration. Payment will be proceeded from your iTunes account during 24 hours before current subscription expiration. User can manage the subscriptions. You can turn off auto-extension after purchase in account settings. Privacy Policy: appcrab.net/privacy-policy Terms of Use: appcrab.net/terms-of-use
