General Chemistry vs Chemical Experiment Simulation Usage & Stats

General Chemistry provides the most essential chemical data and calculators, such as interactive periodic table, chemical elements info, chemical reaction balancer, pH, ideal gas, Molecular Weight and mass percent calculators. The applications presents periodic table of chemical elements, that coloured with respect to the category they belong to. (Metals, Halogens, etc..) Each element can be selected and then pressing the “Element” bar button leads to detailed info page. Additionally the app provides calculators, that target the most common chemical tasks: Balancing chemical reaction equations. Estimation pH of strong and weak, monoprotic or polyprotic acid and base solutions. Ideal gas, pV=nRT, calculator with units conversions. Molecular weight and mass composition analysis. Important notes: Reaction Balancer and Molecular Analysis: Molecular formula format: charge, if exists, must be provided as well, separated by coma: Na,+ ; SO4,2- . Application supports state indexes: (g), (s), (l), (aq) – all are lowercase only, placed at the end of the compound formula. Valid examples: Mg(HCO3)2, CaCl2.2H2O, CaCl2*2H2O, (NH4)2Fe(SO4)2.6H2O, Mg(H2PO4)2, C6H12O6, Na, 2+(aq). Analyser is case sensitive. For stoichiometric analysis of chemical reaction please refer to “Stoichiometry”. pH Calculator: Tapping the first field (Acid Strong 1P) will select the type of the analysed acid or base. Acid Strong 1P – Acid monoprotic, that completely dissociates to electrolytes. Acid Weak 1P – Acid monoprotic, which dissociation is dictated by equilibrium constant Ka1. Acid Weak 2P -Acid biprotic, which dissociates by two stages defined by equilibrium constants Ka1 and Ka2. Base Weak 3P -Base triprotic, which dissociates by three stages defined by equilibrium constants Kb1, Kb2 and Kb2. Estimation of solution pH values is based on advanced quantitative chemical analysis which allows simultaneous calculation of all dissociation stages of acids and bases and water dissociation (Kw). The dissociation constants fields accept both formats: 1) pK values (-log(K)) and 2) regular K values, but only in a particular scientific format, which requires inclusion of exponential part “e” (for example: 1e-5 instead of 0.00001, or 2.5e0 instead of 2.5). Empty dissociation constant field would imply that this dissociation step is “strong” or complete. For acid – base titration and indicators please refer to “Acid Base pH”. Ideal Gas calculator: Fill data for all variables, except the one that must be derived. User can choose the most convenient units for input and output variable before calculation, so the output value will be adjusted for the required units. Touching the units field scrools through the available units.

Chemical Experiment Simulation

Chemical Experiment Simulation is a software that simulates hands-on chemical experiments on mobile phones. At the same time, it also contains a lot of rich chemical knowledge. It is a unique and interesting software. Several important functions in the software: 1. Use your own hands to arbitrarily combine experimental devices on your mobile phone, give play to your imagination, and use your chemical knowledge to create different experimental combinations. At the same time, after the experiment, we will also provide users with the experimental results and the reaction equations used in the experiment, so that users can clearly know the whole chemical reaction process. 2. View and operate case experiments. Several representative chemical experiment cases are built in the software. Users can assemble these case experiment instruments according to the prompts to complete the experiments. We also provide detailed knowledge explanation for each case experiment, so that users can understand the reaction principle and be familiar with the reaction process. 3. Check the chemical elements. The software also includes two parts: intelligent element periodic table and element list. Users can view the information of an element and its related compounds from these two interface functions as needed. At the same time, it also includes a variety of display and arrangement methods, which makes the periodic table more convenient and intelligent. 4. Check the chemicals. The software has built-in more than 100 common chemical substances. Users can find and view some chemical substances in the list of substances. The basic information of these chemical substances is listed in detail in the software, and the common chemical reaction equations involved in these substances are also listed in particular. 5. Check the chemical reaction equation. Hundreds of chemical reaction equations are built into the software, and users can find and view them in the equation list. At the same time, enter the equation details page, and users can also directly conduct experiments according to this equation and directly observe the experimental phenomena. 6. Support rich extension functions. The software allows users to add chemical substances and chemical reaction equations by themselves, and use the newly added substances or equations for experiments, which greatly improves the expansion and richness of the software. 7. The software also adds a function of compound exercise distribution map, according to which users can be familiar with the exercises between various substances. 8. Check the functions of some basic chemistry knowledge. The software has built-in many basic chemical knowledge (such as metal activity sequence table, introduction of common laboratory instruments, etc.), which users can easily view. In short, this software is a systematic expansion of chemical experiments and chemical knowledge. It makes it easier and more interesting for users to observe and learn chemical knowledge.
