CBSE Class 10 chemistry experiments, run online
The chemistry half of Class 10 Science turns on four chapters and the practicals that go with them. Each simulator below matches one of those chapters, gives you the observation the way the record book wants it, and explains what is actually happening in the flask.
Open the digital labTopic by topic
Useful for the practical file, for viva preparation, and for the board questions that ask you to predict an observation rather than recall a definition.
The labs in full
19 experiments matter for this syllabus. Each opens on its own page and is free to use.
Balancing equations
A live atom tally and a mass balance that tips until both sides match.

Bond angles, hybridisation, VSEPR shape and polarity for any molecule.
Open the lab →Common questions
Can I use these for my practical record file?
Yes. Each lab shows the apparatus, the readings and the observation in the order a record book asks for them, so you can write up a proper aim, procedure, observation and conclusion. Do check your school's format - some teachers want a specific layout or a diagram drawn by hand.
Do these cover the CBSE viva questions?
The common ones, yes. Most viva questions ask why an observation happens rather than what it is, and every simulator explains the chemistry next to the apparatus - why the magnesium ribbon is cleaned first, why rusting needs both water and oxygen, why the hydrogen volume is twice the oxygen volume.
Which chapters do these belong to?
Chemical Reactions and Equations, Acids Bases and Salts, Metals and Non-metals, and Carbon and its Compounds are the chemistry chapters in Class 10 Science. The labs are grouped by topic above so you can find the one matching whatever you are on.
Will it work on a phone?
Yes. Every lab is built for a phone screen and several are better in landscape - there is a rotate button on the page to switch.
Studying something else?
The same labs, grouped for a different syllabus.
