Which of the following digestive juices has the minimum $\mathrm{pH}$ value?
- ABile
- Correct answerBGastric juice
- CSaliva
- DPancreatic juice
Solution
Bile is an alkaline viscous fluid, yellow to green in colour and having a $\mathrm{pH}$ of 7.8-8.6. Saliva is secreted by salivary gland and its $\mathrm{pH}$ is about 6.8 . Gastric juice is secreted by the gastric gland in stomach and its $\mathrm{pH}$ value is 1-2.5 and pancreatic juice is colourless watery fluid and slightly alkaline. Its $\mathrm{pH}$ is $7.5-8.0$. Therefore gastric juice has minimum $\mathrm{pH}$ value.
Hence, the correct answer is option: 'B'.
