As the Stomach Churns Lab DAY 1

In our class, we did a lab on digestion.  We had 4 test tubes and we put a substance in each tube.  In tube A, we putted 10ml of enzyme pepsin along with 3 cubes of egg white.  In tube B, we put in 5ml of enzyme pepsin and 5ml of water along with another 3 cubes of egg white.  The substance in tube C was 5ml of enzyme pepsin and 5ml of hydrochloric acid along 3 cubes of egg white.  Finally, in tube D was put in 3 cubes of egg with 10ml of hydrochloric acid.  For each of the tube there was no immediate reaction.  When we put the blue litmus paper in we got a reaction from the tube D.  For day 2 I expect to get a reaction in the tube with hydrochloric acid.  The acid will break down the egg white.
