Reaction Solver for Web Apps

Balancer · Periodic table · Stoichiometry (Inorganic Chemistry focused)

From balancing your very first chemical equation to mastering advanced AP, IB, and some college-level chemistry, The Reaction Solver is the ultimate all-in-one chemistry companion. Built to run 100% OFFLINE with zero internet connection required, Reaction Solver eliminates online distractions, notifications, and ads, providing a quiet, laser-focused environment for homework, lab reports, and exam preparation.

DESIGNED FOR EVERY LEVEL:

• BEGINNERS: Master conservation of mass without frustration. Automatic typo correction, formula formatting, and quick-insert chemical keys prevent syntax errors.

• MIDDLE SCHOOL: Explore synthesis, decomposition, and single replacement with instant element-by-element atom counts.

• HIGH SCHOOL & AP/IB: Solve complex redox reactions, net ionic equations, precipitation, Bronsted-Lowry acid-base equilibria, electrochemistry, and chemical kinetics.

100% OFFLINE & ZERO DISTRACTION:

• No Wi-Fi or mobile data needed, making it ideal for classrooms, libraries, buses, and offline exams.

• Zero ads, zero pop-ups, and zero background tracking.

• Complete student privacy: all linear algebra and prediction logic run directly on your device.

POWERFUL FEATURES & BENEFITS:

1. EXACT EQUATION BALANCER Balance molecular, ionic, and skeletal equations using exact integer linear algebra. Instant visual verification badges confirm atom and charge conservation (Balanced, Atoms conserved, Charge conserved).

2. SMART REACTION PREDICTOR Enter only the reactants and our deterministic offline rule engine identifies the reaction class and predicts products for displacement, combustion, precipitation, acid-base, and decomposition. Explains possible pathways when conditions dictate multiple outcomes.

3. STEP-BY-STEP REDOX SOLVER Break down difficult oxidation-reduction equations using the pedagogical ion-electron half-reaction method. Choose or auto-detect Acidic, Basic, or Neutral media, with full visibility into oxidation states, electron transfer, and balanced half-reactions.

4. REAL-TIME STOICHIOMETRY CALCULATOR Dynamic stoichiometry table directly linked to your balanced equation. Enter grams, moles, or molecules for any reactant or product; all stoichiometric ratios, molar masses, and theoretical yields recalculate instantly.

5. 118-ELEMENT PERIODIC TABLE Interactive, tap-to-inspect periodic table covering Hydrogen to Oganesson. View atomic masses, electronegativity, electron configurations, oxidation numbers, and periodic classifications with a single tap.

6. ELECTROCHEMISTRY & GALVANIC CELLS Access local standard reduction potentials. Automatically calculate cell potential, standard Gibbs free energy, and reaction spontaneity.

7. CHEMICAL KINETICS TOOL Compute integrated rate laws for zero, first, and second-order reactions, radioactive and chemical half-lives, and Arrhenius activation energy.

8. QUALITATIVE ANALYSIS & COMPLEX CLEAVAGE Includes built-in analytical rules for cation and anion flame and precipitation tests (cobaltinitrite for potassium, pyroantimonate for sodium, Nessler's reagent for ammonium, ferrocyanide/ferricyanide) plus reversible complex-ion dissociation (such as K2HgI4 splitting into 2KI + HgI2).

9. SMART SYNTAX & TYPO ASSISTANT Automatically detects lowercase element slips (like cacl2 to CaCl2), spaced charges, zero versus letter O, and offers one-tap auto-corrections.

10. TOUCH-FRIENDLY CHEMICAL KEYBOARD Includes dedicated quick-insert buttons for common elements (C, H, O, N, Na, Cl, Fe, Cu), parentheses, plus signs, and numeric subscripts (2, 3, 4).

11. BUILT-IN CAPABILITY MANUAL & OFFLINE SAVED REACTIONS Includes a complete in-app reference guide and optional local bookmarking to save custom reactions for later review.

12. The app is mainly focused on inorganic chemistry reaction solving but it can handle US high school level organic chemistry reactions.

13. People work professionally with chemicals can try this app for general use cases.
