The concentration is approximately 0.00000004 Eq/L. Because is would be cumbersome to express concentrations with these small numbers, pH is used to express the H+ ion concentration. An acid is a substance that donates hydrogen ions and therefore increases the H+ ion concentration of a solution, which in turn causes the pH to fall (acidosis).

Sulfuric acid. H2SO4 → H + + HSO4 – ... Therefore, nitric acid will have a higher concentration of hydrogen ions than acetic acid, which makes the nitric acid corrosive. Acetic acid on the other hand is a weak acid. This classification means that solution of acetic acid contains more acid molecules that H+ ions. ... One – Normal solution ...

Acid in your stomach has a normal pH of 2. This acid helps in the digestion of food and kills off bacteria. If you eat too quickly, or are under stress, your stomach produces an excess amount of gastric acid (giving you heartburn). To neutralize the excess acid, an antacid tablet is swallowed. This antacid is a …

Conductivity Titration of a Ba(OH)2 solution with H2SO4. In this experiment, you will monitor conductivity during the reaction between aqueous solutions of sulfuric acid, H2SO4, and barium hydroxide, Ba(OH)2, in order to determine the equivalence point. From this information, you can find the molar concentration of the Ba(OH)2 solution.
