About Mini Chemistry
Part of Mini Education
Chemistry gets easier when the ideas behind each reaction and calculation click. Our notes, examples and practice help you build that understanding, then use it with confidence.

The people behind the pages
Who we are
The MiniEducation Team creates and maintains the lessons, examples and practice on this site. We check our work against the relevant syllabus, revisit pages when something changes and welcome corrections from readers.
Mini Chemistry is an independent learning resource. We are not affiliated with Cambridge, SEAB or any school.

How we work
Made to make sense
We aim for explanations that show the chemistry behind observations, use the right conditions and units, and make each step in a calculation clear. Our editorial checks are internal and we welcome corrections when a page falls short.
