Which of the following digestive juices has the minimum pH value?
Bile
Gastric juice
Saliva
Pancreatic juice
B.
Gastric juice
Bile is an alkaline viscous fluid, yellow to green in colour and having a pH of 7.8- 8.6.
Saliva is secreted by salivary gland and its pH is about 6.8.
Gastric juice is secreted by the gastric gland in stomach and its pH value is 1- 2.5.
Pancreatic juice is colourless watery fluid and slightly alkaline. Its pH is 7.5-8.0.
Therefore, gastric juice has minimum pH value.
