The prostate gland secretion helps neutralize seminal fluid because it is alkaline in nature. This alkaline fluid, which makes up a significant portion of semen, helps neutralize the acidic environment of the urethra and vaginal tract, providing a more hospitable environment for sperm survival and motility. Additionally, the alkaline nature of prostate secretion may also help protect sperm from the acidic environment of the female reproductive tract.
kills bacteria activates pepsinogen to decrease the Ph level ( make it more acidic)
add lime...
The secretions of the stomach are acidic. The acid is too strong than you can imagine. The pH is as low as 2. The secretions of the stomach remain acidic till the mid-part of the second part of the duodenum. Here the alkaline secretions of the liver and the pancreas enter the duodenum to counter the acidic secretions of the stomach.
No, milk is itself slightly acidic. Depending on the concentration of the acid you are trying to neutralize, you could dilute it a bit, but it would still be acidic.
