What is the independent and dependent variable in Electrolysis of water experiment

Electrolysis of water
Use a U-tube with electrodes at each end, connected to a battery. Fill the U-tube with water. Turning on the battery, observe the results at each electrode. Next, test for hydrogen and oxygen gas produced at each end of the tube.


Sagot :

Dependent could be the amount of water, the time that you are using in the u tube. Independent could be the amount of hydrogen and oxygen gass.




Remember, dependent variable is something that you control or measurement. Like for example. You have 2 different tubes one with 5ml of water and the other one with 10ml.

Independent something you cannot control. Like the amount of light can a plant receive or how much long it will take water to boil depending on the how high the fire is
