Procedure:1. Calibrate an eyedropper by carefully counting the number of drops it takes to fill a10 ml graduated cylinder to the 2.0 ml mark. Hold the dropper vertical and do nottouch the sides of the cylinder. Repeat the measurement twice and take the averageof the three values. Divide the 2 ml by the average number of drops to obtain theVOLUME (ml) PER DROP. Use this calibrated dropper for the titration later.2. Put 80 ml of pink tap water-phenolphthalein solution (to be prepared by theinstructor) in a 100 ml graduated cylinder and carefully add a small fish. Recordvolume of the fish and note the starting time.3. Pour the contents into a clean plastic cup. Put 80 ml of the same solution intoanother flask to serve as the reference.4. Observe the color of the solution in the experimental flask against a whitebackground. If the solution becomes clear in less than 30 minutes, terminate theexperiment and record the elapsed time. If it hasn't cleared by 30 minutes, terminateit then. Carefully remove the fish and return to its proper place.5. If solution remains pink, add 0.01N sulfuric acid dropwise using your calibrateddropper to both reference and experimental flask until solution clears. Recordnumber of drops in the table.6. Make 3 trials. Use different fish in every trial.

The main ai of this experiment is to determine the buffering capacity of fish blood using a…
