About Chemixa

Chemixa is a free chemistry learning platform built around one idea: every concept should come with its data, its calculator and its practice — all connected.

## What you will find here

• Concept guides across atomic structure, bonding, stoichiometry, acids and bases, thermodynamics, organic and nuclear chemistry
• A complete element reference — every element with its properties, plus compound and ion libraries
• An interactive periodic table and an equation balancer that shows each balancing step
• Step-by-step calculators for molarity, dilutions, pH, molar mass and more — formula, substitution and answer shown
• Worked examples solved the way a good teacher solves them
• Practice problems with instant feedback and explanations
• A glossary, formula library, and unit, constant and symbol references

## Who it is for

High-school and introductory-college students, self-learners, teachers, tutors and parents — anyone who wants chemistry to finally click.

## Our principles

1. Understanding first. Every topic starts with what the particles are actually doing before the equations arrive.
2. No black boxes. Calculators and the balancer show every step; data pages state their values plainly.
3. Honest science. Element data, constants and worked numbers are checked against standard references. When we are unsure, we say so.
4. Free forever. No account, no paywall, no login required to learn.

## Corrections

Found a mistake — a wrong molar mass, a misbalanced equation, a typo in a data table? Our corrections policy explains how we fix errors transparently. See the Corrections page.
