General Chemistry Remote Lab Free Resources
Simulates addition of acid and base to a solution. No planned structure to this lab.
Acid/base of water
Cool lab that runs an actual titration for you with complete data. Requires instruction in how to use/what to run:
pH scale and how it works. No structure.
Ka expressions
Simple mix and match to see how K changes with diff acid/base strengths
Titration curves – can vary acid/base strength and indicator
Atomic Interactions/Nuclear Chemistry
Lets you vary some conditions
Clear experiment – outlined well
Atomic and Molecular Structure
Simulates distance between atoms of Ne, Ar, O. Some info on IMF. No planned structure to this lab.
Building an atom from p, n, e. Comes with info about symbols and a game to play.
Check out ISOTOPES and Atomic mass
This is moles and mass
Molecular shape and structure
Balancing Chemical Equations
Game play. Comes with introduction to help.
Moles, mostly, and how it relates. Comes with a game play.
Concentration lab, no structure. And Beer’s Law relating to concentration in a separate lab, no structure.
What happens when electrons are excited:
Complete lab!
Pretty simple, very straightforward.
Coulomb’s Law
Macro and atomic scale investigation into Coulomb’s law. No structure.
No structure to this lab. Needs a lot of guidance for students to understand what is going on.
Simple labs, no planned structure
Slightly confusing:
Throwing in a little chromatography and partition coefficients!
Simple P/T dependence on various simple gases
Ideal Gas law
Kinetic mol theory
No structure to this lab. Needs a lot of guidance for students to understand what is going on.
Compares two hypothetical atoms to three hypothetical atoms to real atoms. Lots of ability to vary electronegativity of each hypothetical. No structure to this lab.
Give syou control over variables
Iodine clock reaction – complete experiment
slightly confusing, but seems cool:
Periodic Trends
Super simple lab. No structure
batteries lab – complete experiment
electrochemical cells – complete experiment
Lets you play around with various concentrations of solute in low solubility solids.
solubility and the impact of pH
Solubility rules. V. straightforward
Qualitative analysis, clear experimental details
States of Matter
Super basic.
Super simple labs, no structure
What are thermodynamic values of a reaction? Actually just like a reference table, but more interactive.
Coffee cup calorimeter, clear experiment
Bomb calorimeter (no download necessary)
Comprehensive labs
Given five samples, students must test and review what happens. Complete experiment, well thought out.
Electrolyte solutions and conductivity
