Measure of abiotic factors of the aquarium
Oxygen content
Oxygen content
Material:
Water of the aquarium, GTR, Interface, oxygen electrode and distillated water for the oxygen electrode.
Experiment set-up:
First we connected the measuring tool (Interface) with the calculator (GTR) and also the oxygen electrode. Then we took the electrode which was in the distillated water before and put it into the aquarium water.
Observation:
First of all we’ve recognised a lot of values of the oxygen concentration, but then it stopped by 6mg/l.
Explanation:
By dipping the oxygen electrode into the water, the oxygen concentration in the water changes all the time until the value stabilised.
