What difference(s) do you observe in the cups with and without baking soda as a carbon source? How does the detergent help the leaf disks to sink? What is the purpose of the baking soda solution? Why do the leaf disks in the baking soda solution (treatment) begin to float? Why don't the leaves in the baking soda solution continue to produce oxygen in the dark? If the light-independent reaction can run without light, why does oxygen production (and presumably glucose production) stop? How long did it take for half of the leaf disks to float in each cup?

Potentiometric Titrations

Potentiometric titration is one of the important titration methods and is mainly carried out to characterize acid solutions. It follows a method similar to that of the normal titration technique, but the main difference is that there is no indicator used in the potentiometric titrations. Instead of using an indicator, electrodes are employed for monitoring the whole titration process. A scientist named Robert Behrend did the potentiometric titration for the first time, and it was done using the mercurous solution and potassium chloride.
