1:30 Aluminum + Copper (II) Chloride Single Displacement chemistNATE 116 views 1 month ago Watch Aluminum turn into copper in SECONDS. I cut the video short because the copper metal floated out of view of the camera. That's how fast it happened. Believe that.
3:42 Does Keq Change with Temperature? chemistNATE 113 views 1 month ago Keq DOES change with temperature, but not by much. Here, I show why, using the Arrhenius Equation (which relates reaction rate to temperature and activation energy). You ...
5:08 What concentration of solid will dissolve? (EASY METHOD) chemistNATE 112 views 1 month ago This is the fastest way to figure out the Saturation Concentration of a solid. What will be the concentration at saturation? All you need is the Ksp and to know what the ...
6:34 What mass will Dissolve in 1 L of Water? (Use Ksp) chemistNATE 160 views 1 month ago How to Calculate how much PbI2 will dissolve in 1 L of water? I use PbI2 as an example....you can do this for any solid as long as you have its solubility product constant...
3:40 What is Ksp? (Solubility Product Constant) chemistNATE 547 views 2 months ago Ksp is really just an equilibrium constant (Keq), but it's for a solid dissolving in water. This is special, since all of the reactants are solid, and so they AREN'T inclu...
3:38 Balance a Redox Reaction (BASIC solution) chemistNATE 1,007 views 2 months ago How to balance a redox reaction in basic solution. Same process as balancing in acidic solution, with one extra step: 1. Make sure electrons gained = electrons lost 2. Ad...
7:51 Balance a Redox Reaction (ACIDIC solution) chemistNATE 1,294 views 2 months ago How to balance a Redox Reaction in Acidic solution. 1. Make sure electrons gained = electrons lost 2. Add H2O to whichever side doesn't have enough O 3. Add H+ to whicheve...
6:46 Is it a Redox Reaction? chemistNATE 216 views 2 months ago How can you determine if a given chemical reaction is a redox reaction or not? Assign oxidation numbers to each of the atoms. If any of the oxidation numbers changed, you...
6:56 Oxidation Number of Carbon (Can be anything from -4 to +4 !!!) chemistNATE 188 views 2 months ago Did you know carbon can have an oxidation number of anything from -4 up to +4? In fact, as you "oxidize" an organic compound like ethane, the "oxidation number" or carbon ...
9:37 How to Figure out Oxidation Numbers chemistNATE 582 views 2 months ago How to assign oxidation numbers to the atoms in a molecule. 1. Elements have oxidation number = 0 2. Hydrogen's always +1 (except in "hydrides") 3. Oxygen's always -2 (exc...

About Chemistry Problems Solved

CURRENTLY TAKING REQUESTS

What chemistry questions do you want solved? Tell me in the "Channel Comments" section ...

This channel has how-to videos on solving basic chemistry problems. I hope they are useful to high school and university students who want to see a problem worked through, instead of trying to figure out what their textbook is telling them to do.
