Chemical Solution is a versatile tool forpreparation of simple and complex chemical solutions. App helps tocalculate the solution parameters upon mixing, dilution anddissolution, and solve various problems, like finding solute molesand weights and solvent volumes.Application provides users with personal support through a service,which is intended to aid the undergraduate students with numerouschemistry subjects. The involved students may submit questionsdirectly to developer.The first activity calculates the concentrations, moles and molarratios, etc. of the final solution formed by mixture of severalsolutions or by simple dilution with solvent.In most complicated case, user may input parameters of threeinitial solutions, which are going to be mixed, and optionallyvolume of solvent (to dilute) and then press "Calculate" to findmolar concentration and total volume of the final mixture, molesand molar ratios of all solutes. Except that, this activity may beused for plenty of small things:•Simple dilution: add one solution (by filling all required fields)and pure solvent to get what portions of solution and solvent youneed, to dilute solution from, let’s say, 2M to 25mM.•When molar weight of solute is available, then final concentrationin mg per ml (mg/ml is equal to g/l) can be calculated, which ishelpful for actual preparation of solution.•When initial solution concentration is provided in mg/ml, thenmolar weights of solutes are required, and application will findmoles and molar concentrations.•In the similar way, moles of solute can be found, just by usingone solution row. Input Mw, concentration in mg/ml and requiredvolume and press “Calculate”.The second activity deals with solid solutes (powders) dissolution.It provides total molarity, molality, mass/volume concentration,moles and molar ratios of dissolved solutes, based upon molarweights, dissolved masses and final solution density.This app is part of Chemistry and Biochemistry and ChemicalEngineering Lab Pack including several apps dealing with chemicalsolutions, reaction equilibrium, kinetics, acid base neutralisationreaction, titration, and liposome preparation.The preparation of the desired solutions may be further facilitatedby using Chemical Solution Wizard app and deprotonation kineticsand equilibrium may be followed by using Chemical Kinetics andChemical Equilibrium apps. Solubility and precipitation problemsare targeted by Solubility Products app. Additionally, acid basetitration and pH calculations are facilitated by Acid Base pH app.pH values of the compounds having numerous functional groups(carboxylic and amino-derivatives, like amino acids) can becalculated and plotted by means of Isoelectric Point app.

"A majority of industrial processes occur insolutions. A solution consists of at least two components, thesolvent and the solute. Is it important to keep a track of just howmuch of the solute has to be dissolved in how much of a solvent?Well, Yes!So, how does one do that?Here is an app that makes an effort to address all your queries ina manner you will find highly engrossing and delightful. Beginningwith the relation between the colour of a solution and itsconcentration, it extends further and explains the intricaciespertaining to the calculations involved in measuring theconcentrations of solutions in a very simple manner.To reinforce your knowledge on the topic, the video is supplementedwith a quiz, keyterms and relevant images. You can also link toother websites to expand your understanding of thephenomenon.We, at Designmate, help you learn science better making it allalong a pleasant experience. Carefully-thought-out anduser-friendly techniques are our forte which compel the learner toaspire for more and more.Here is wishing you success in your exploration."Keywords: education, eureka.in, molar, chemistry, concentration,temperature, Avogadro, molar mass.
