Vinegar is a weak form of acetic acid used in salad dressing acid. Citrus fruits. For example, stomach acid has a pH of 2 or 3, which means that it is very acidic and has lots of hydrogen ions. The juice produced by boiling red cabbage is useful for determining pH. What do acidic solutions have high concentrations of ? 3.
Hydrochloric acid has many uses. It is used in the production of chlorides, fertilizers, and dyes, in electroplating, and in the photographic, textile, and rubber industries.
Inside your stomach, excess hydrochloric acid is neutralized by the antacid. NaOH, the next step of the lab will involve determining the concentration of the HCl. Once. solution from the buret and not to overshoot the titration endpoint.
