Stomach Acid and Antacid

The video tutorial demonstrates an experiment simulating stomach conditions to observe food breakdown and the effect of antacids. Using boiled egg white, pepsin, hydrochloric acid, and antacid tablets, the experiment shows how gastric acid aids protein digestion and how antacids can neutralize acidity, affecting enzyme activity. The procedure involves dissolving pepsin in acid, adding it to egg white, and comparing it with a mixture containing antacid. Observations reveal that the egg white without antacid dissolves, while the one with antacid remains, illustrating the role of acidity in digestion.
