## What is Chemistry Calc Suite?

Unlock the tools of a modern chemistry lab—right in your pocket.

Chemistry Calc Suite gathers 80-plus carefully curated calculators covering every major branch of chemistry so you can concentrate on thinking, not number-crunching.

◆ Study smarter
- Replace cluttered formula sheets with tap-ready solvers for atomic mass, electron configuration, pKa, dilution, titration, mole-to-gram conversions and more.
- Step-by-step explanations reveal how each answer is built—ideal for homework checks and exam revision.
- Color-coded inputs flag missing data instantly, so you always know what to measure next.

◆ All of chemistry, one tap away
- General chemistry: atoms, molar mass, bond order, electronegativity, percent composition
- Stoichiometry: Avogadro, mole/gram converters, molarity, normality, ppm ↔ M conversions
- Solutions & mixtures: Henderson–Hasselbalch buffers, serial dilutions, pH, TDS, water hardness
- Kinetics & equilibria: Arrhenius, rate constants, equilibrium Kc/Kₚ, reaction quotient Q
- Thermodynamics: Gibbs free energy, entropy, boiling-/freezing-point shifts, vapor pressure
- Electrochemistry: cell EMF, Nernst equation, Faraday electrolysis, ionic strength
- Physical chemistry: diffusion/effusion, osmotic & partial pressures, surface tension
- Organic & biochemistry: combustion analysis, degree of unsaturation, Michaelis–Menten, pI, enzyme activity


◆ Why pick this app?
- Offline first. Every solver works without internet—perfect for remote field sites or exam halls.
- Continually expanding. New calculators arrive through free updates; send feedback and see it appear in the next release.


Whether you’re a first-year undergraduate balancing equations, a PhD candidate processing titration curves, or an environmental analyst estimating COD on-site, Chemistry Calc Suite is the fastest route from problem to answer.

Download today and turn complex chemistry into a one-tap solution.
