Your stomach fluid would be neutral (neither acidic nor basic) and you would have extreme difficulty in digesting food.
when acid is added to a substance in the pH, the substance rises in a pressurized state
The pH drops. The stronger the acid the lower the pH.
If the solution is not basic then the pH will fall below 7
As more acid is added to a solution, the pH of the solution decreases. This is because acids release hydrogen ions into the solution, increasing the concentration of H+ ions and lowering the pH.
The pH of water decreases when hydrochloric acid is added to it because hydrochloric acid is a strong acid that donates protons in water, increasing the concentration of hydrogen ions and lowering the pH of the solution.

When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.

Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
it changes its colour into red.
A small amount of acid is added to a buffer solution. The pH of the solution will stay about the same.
sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
When citric acid is added, or any acid for that matter, the pH of a substance will decrease. This is because since acids have a low pH they will decrease the pH of other substances when added to it.
The formula to calculate the change in pH when a strong acid is added to a buffer solution is pH -log(H/HA), where H is the concentration of hydrogen ions and HA is the concentration of the weak acid in the buffer solution.
