KAGAKU
See chemistry before formulas
Free · Designed for iPad. Not verified for macOS.
See chemistry come alive: 118 elements, 3D molecules, flame spectra, titration curves, the Daniell cell, gas-law particles — all interactive, all visual.
KAGAKU is a visual-first educational app for learning chemistry through direct interaction with simulations.
The 10th installment in the SUUGAKU / BUTURAKU / DENRAKU / HARAKU / NETURAKU / SEIRAKU / KORAKU / RYORAKU / RYURAKU / KAKURAKU series. This time the theme is "chemistry." Ten core topics from high-school to introductory-university level, all delivered through beautiful animations and hands-on manipulation.
[10 Features]
▶ Periodic Table
All 118 elements color-coded by category. Tap any element to see its atomic number, mass, electron configuration, and electronegativity.
▶ Atom Structure
Animated Bohr model. Watch electrons orbit quantized shells for 13 representative elements (H through Cu).
▶ 3D Molecules
12 molecules rendered as ball-and-stick models: water, methane, ammonia, CO₂, ethanol, benzene, ethylene, acetylene, glucose, and more. Drag to rotate, or let them auto-spin.
▶ Chemical Bonds
Visualize ionic, covalent, and metallic bonding. Electronegativity difference auto-classifies the bond type; animations highlight the distinct electron behavior of each.
▶ Equation Balancer
Six reactions: methane combustion, iron oxidation, water synthesis, Haber process, photosynthesis, and neutralization. One tap reveals balanced coefficients plus an atom-count check for each element.
▶ Flame Test
Li, Na, K, Ca, Sr, Ba, Cu — watch each element burn with its signature color above a Bunsen burner, alongside the emission spectrum with wavelength labels (nm).
▶ Acid-Base / pH
Real-time strong-acid / strong-base titration curve. Switch between BTB, phenolphthalein, and methyl orange indicators and see color change with pH.
▶ Electrochemistry
Animated Daniell cell. Electrons flow through the external circuit, Zn²⁺ and Cu²⁺ ions drift in the solutions, EMF 1.10 V is displayed live.
▶ Gas Laws
PV=nRT particle simulation. Freely change temperature, volume, and particle count and watch Brownian motion drive wall collisions — the source of pressure.
▶ Organic Chemistry
A visual field guide to alkanes, alkenes, alkynes, aromatics, and functional groups (-OH, -NH₂, carbonyl). Eight representative molecules you can rotate in 3D while learning their properties.
