General Chemistry Remote Lab Free Resources
Acid-Bases
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
Buffers
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
Polarity:
Balancing Chemical Equations
Game play. Comes with introduction to help.
Moles, mostly, and how it relates. Comes with a game play.
Light
Concentration lab, no structure. And Beer’s Law relating to concentration in a separate lab, no structure.
Abs/emission
What happens when electrons are excited:
Spectrophotometry
Complete lab!
Colorimetry
Concentration
Pretty simple, very straightforward.
Coulomb’s Law
Macro and atomic scale investigation into Coulomb’s law. No structure.
Density
Energy
No structure to this lab. Needs a lot of guidance for students to understand what is going on.
Equilibrium
Simple labs, no planned structure
Slightly confusing:
Throwing in a little chromatography and partition coefficients!
Gases
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.
IMF
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.
Rate
Give syou control over variables
Iodine clock reaction – complete experiment
slightly confusing, but seems cool:
Periodic Trends
Redox
Super simple lab. No structure
batteries lab – complete experiment
electrochemical cells – complete experiment
Solubility
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.
Thermodynamics
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
