Acid
The approximate pH of gastric fluid is around 2.5pH to 3.5pH
No, saliva is not a gastric fluid. Saliva is produced by the salivary glands in the mouth and helps with the initial stages of digestion by breaking down food particles. Gastric fluid, on the other hand, is produced in the stomach and consists of hydrochloric acid and digestive enzymes.

An ulcer can develop when the mucous coating of the stomach breaks down, allowing the enzymes contained in gastric fluid to eat through the stomach lining.

Hydrochloric acid is the main acid present in gastric fluid, typically at a concentration of about 0.5% to 1.5%. This strong acid helps to break down food in the stomach and create an acidic environment that is essential for digestion and the activation of enzymes.
The fluid in your mouth contains an enzyme called amylase, which helps to break down carbohydrates into simpler sugars during the process of digestion.

Gastric fluid would be hydrochloric acid. Calcium carbonate would be a common neutralizer. CaCO3 + 2HCl -> CaCl2 + CO2 + H2O a salt, water and carbon dioxide gas ( burp!) as products of this neutralization reaction.
Saliva is an enzyme-containing fluid in the mouth. It starts the process of chemical digestion in the mouth, and is the first set of digestive chemicals with which the food you eat comes into contact.
