Isotopes API
Atomare Isotopen-Referenzdaten als API, basierend auf den NIST Atomic Weights and Isotopic Compositions. Für jedes bekannte Nuklid: sein Element (Ordnungszahl Z und Symbol), Massenzahl, relative Atommasse, natürliche Isotopenzusammensetzung (Häufigkeit) und die Standard-Atommasse des Elements. Suchen Sie ein Isotop nach Bezeichnung (C-12, U-238) oder nach Symbol + Masse, listen Sie alle Isotope eines Elements auf, ordnen Sie Isotope nach Masse oder natürlicher Häufigkeit oder suchen Sie. Eine präzise physikalische und chemische Referenz für Wissenschaft, Bildung, Labor- und Ingenieuranwendungen. Unterscheidet sich von elementaren Daten.

Electrolysis API
Faraday-law electrolysis maths as an API, computed locally and deterministically. The mass endpoint applies Faraday's first law of electrolysis, m = (Q·M)/(n·F) = (I·t·M)/(n·F), to give the mass of a substance deposited at a cathode or dissolved at an anode from the charge passed — or the current and time — the molar mass and the valence (electrons transferred per ion), with the Faraday constant 96485 C/mol. The charge endpoint inverts it to give the charge Q = (m·n·F)/M and, with a current, the plating time needed to deposit a target mass — the core sizing calculation for electroplating and anodising. The gas-volume endpoint computes the volume of gas evolved during electrolysis, moles = Q/(n·F) and volume = moles × 22.414 L/mol at STP, using the electrons per gas molecule (two for hydrogen, four for oxygen in water electrolysis). Molar mass is in g/mol, current in amperes, time in seconds, charge in coulombs and mass in grams. Everything is computed locally and deterministically, so it is instant and private. Ideal for electroplating, anodising, battery, hydrogen-production and chemistry-education app developers, plating-time and gas-yield tools, and electrochemistry teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is electrolysis (Faraday's laws); for cell potential and the Nernst equation use an electrochemistry Nernst API.

Colligative Properties API
Colligative-properties chemistry maths as an API, computed locally and deterministically. The freezing-point endpoint computes the freezing-point depression ΔTf = i·Kf·m and the resulting lowered freezing point of a solution, from the molality, the cryoscopic constant (1.86 °C·kg/mol for water) and the van 't Hoff factor i — which is 1 for a non-electrolyte like sugar, about 2 for sodium chloride and about 3 for calcium chloride. The boiling-point endpoint computes the boiling-point elevation ΔTb = i·Kb·m and the raised boiling point, with the ebullioscopic constant (0.512 °C·kg/mol for water). The osmotic-pressure endpoint computes the van 't Hoff osmotic pressure Π = i·M·R·T from the molarity, the temperature and the van 't Hoff factor, the pressure that drives osmosis across a semipermeable membrane, returned in atmospheres, kilopascals and bar. Molality is in mol per kg of solvent, molarity in mol per litre of solution and temperature in kelvin. Everything is computed locally and deterministically, so it is instant and private. Ideal for chemistry-education, food-science, antifreeze, desalination and biology app developers, solution and de-icing tools, and STEM teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is colligative properties of solutions; for a compound's molar mass use a molar-mass API and for dilution concentrations a dilution API.

API de Estequiometría de Reacciones
Matemáticas de estequiometría de reacciones químicas como API, calculadas local y determinísticamente. El endpoint de reactivo limitante toma dos reactivos con sus cantidades en moles y sus coeficientes de ecuación balanceada y determina cuál se agota primero — el reactivo limitante — comparando la relación moles/coeficiente (el avance de la reacción), y devuelve cuánto del reactivo en exceso sobra. El endpoint de rendimiento calcula el rendimiento teórico de un producto, en moles y gramos, a partir del reactivo limitante y el coeficiente estequiométrico y la masa molar del producto, n_producto = n_limitante·(coef_producto/coef_limitante), y — dado el rendimiento real — el rendimiento porcentual. El endpoint de mol-masa convierte entre moles, masa y número de partículas para una masa molar dada, usando moles = masa / masa_molar y N = moles · número de Avogadro (6.02214076e23). Las cantidades están en moles, las masas en gramos y las masas molares en g/mol. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de educación química, laboratorio, farmacéuticas e ingeniería química, herramientas de planificación de reacciones y rendimiento, y enseñanza STEM. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es estequiometría de reacciones; para la masa molar de un compuesto a partir de su fórmula use una API de masa molar y para concentraciones de soluciones una API de dilución.

Electrochemistry Nernst API
Electrochemistry maths as an API, computed locally and deterministically. The nernst endpoint applies the Nernst equation, E = E° − (R·T/nF)·ln Q, to give the actual electrode or cell potential under non-standard conditions from the standard potential E°, the number of electrons transferred n, the reaction quotient Q and the temperature — at 25 °C this reduces to E = E° − (0.05916/n)·log10 Q, and a larger Q (more product) lowers the potential. The cell-potential endpoint computes a galvanic cell's standard EMF from the cathode and anode standard reduction potentials, E°cell = E°cathode − E°anode, together with the standard Gibbs free energy ΔG° = −nF·E°cell and whether the reaction is spontaneous. The equilibrium endpoint computes the equilibrium constant of a redox reaction, K = exp(nF·E°cell / RT), and the corresponding ΔG°, from the standard cell potential and the electrons transferred. Potentials are in volts, energies in kJ/mol, the Faraday constant is 96485 C/mol and the gas constant 8.314 J/mol·K. Everything is computed locally and deterministically, so it is instant and private. Ideal for chemistry-education, battery, corrosion, electroplating and electroanalytical app developers, galvanic-cell and redox tools, and STEM teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is electrochemistry; for acid-base pH use a pH API and for reaction-rate kinetics an Arrhenius API.
