Question #26334
whats a chemical that will counteract lactic acid by changing a color ?
Expert's answer
Lactic acid is a compound that can produce H+ (or H3O+) ions after dissolving. This ions can be detected by indicators. A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or basicity) of the solution can be determined visually. Hence a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+) in the Arrhenius model. Normally, the indicator causes the colour of the solution to change depending on the pH. Indicators can also show change in other physical properties; for example, olfactory indicators show change in their odor.
