Digestion Lab Response Blog

What we did in this lab was work with two types of acid. We were showing how digesting works like how the acid in our stomach breaks down the food. We had 4 beakers, we labeled them A B C D. A just had pepsin, B had Pepsin and water. C had just hydrochloric acid. D is a mix of Hydrochloric acid and Pepsin. We put 3 pieces of eggwhites inside each beaker. A and C are controls. They were just to see how they worked by themselves. On day 1 we checked if there were any imediate reaction. All of the beakers didn't have a reaction. That showed that digestion doesn't happen quickly. Also we tested if they were acidic. A and B were not but C and D are. The next day nothing happened for all of them except D. In the beaker D the eggs got smaller. Then we checked if it got more or less acidic. A and B were not acidic but C was very acidic and D was very acidic to. At the end of the day we tested there ph and B was less acidic then distilled water. C was more acidic than B. Last was D which was really acidic. The most acidic.
