Sophia: Strong and Weak Electrolytes: Lesson 1
This lesson will explain that some solutes dissociate more readily than others in aqueous solutions and that the greater the ability the stronger the electrolyte. It is 1 of 2 in the series titled "Strong and Weak Electrolytes."
Khan Academy
Khan Academy: Batteries: Electrolyte (Temperature Test)
Here we experiment with hot vs. cold vinegar as our electrolyte. Does the deflection in our galvanometer depend on temperature? Why? Watch this video lecture to find out. [1:37]
Khan Academy
Khan Academy: Batteries: Electrolyte (Salt Test)
Video lectures explores what happens to the deflection when we add salt to an electrolyte. Why? [1:04]
Khan Academy
Khan Academy: Batteries: Electrolyte Test (Pure Water vs. Vinegar)
First we attach our galvanometer to a piece of copper and zinc. Then we submerge the metals in pure water and vinegar. What is the difference? Why? Watch this video lecture to find out. [1:23]
Khan Academy
Khan Academy: Batteries: Electrolyte (Strong Acid Test)
Video lecture explores experimenting with a strong acid as electrolyte and observing the change in deflection compared to weak acid (vinegar). [0:44]
Khan Academy
Khan Academy: Batteries: How Much Electrolyte Does a Single Cell Need?
Observation: when we pull our cell out of the electrolyte it still causes a deflection, which increases when pressure is applied. How could this lead to more efficient batteries? [0:40]
