We had an experiment on dialysis wherein a positive result is expected but unfortunately, we saw no reaction. we did it again but still nothing happened. this is how we did it.1. dissolve 1 pc chicken buoillon in 50ml of hot water.2. pour 25ml of the dissolved chicken buoillon inside a 10 cm longganisa membrane.3. make sure to tie both ends with string and check if there are leaks.4. wash it with distilled water.5. place it in a beaker with distilled water. 3/4 of the longganisa membrane should be dipped in the water.6. leave it that way for an hour.7. get 1ml of the dialysate (water in the beaker where the longganisa is sunk). add 1ml 10% NaOH then 5 drops of copper sulfate(aqueous).8. observe the reaction.Pls help me with this... i need it badly...Thank you...
