Acid-base indicators can distinguish between an acid and a base by exhibiting distinct color changes at different pH levels. For example, litmus paper turns red in acidic conditions and blue in basic conditions. Phenolphthalein is colorless in acidic solutions but turns pink in basic solutions. Methyl orange is red in acidic solutions and changes to yellow and then orange in increasingly basic environments. By adding a small amount of the indicator to the solution of interest, the observed color change provides a visual indication of whether the solution is acidic, neutral, or basic, allowing for qualitative pH assessment.

Yes, the amount of H⁺ or OH⁻ ions present in a solution can be quantitatively determined through techniques like titration or pH measurement. In titration, a known concentration of a base or acid is gradually added to the solution until the equivalence point is reached, allowing the determination of the unknown concentration. pH measurement, using a pH meter or indicators, provides a quantitative measure of the hydrogen ion concentration. The pH scale directly correlates with H⁺ ion concentration in a logarithmic manner. These methods enable precise quantification of acidity or alkalinity in a solution.
The strength of a given acid or base can be judged by its ability to ionize or dissociate in water. Strong acids and bases completely ionize in solution, producing a high concentration of H⁺ or OH⁻ ions, respectively.

The strength of a given acid or base can be judged by its ability to ionize or dissociate in water. Strong acids and bases completely ionize in solution, producing a high concentration of H⁺ or OH⁻ ions, respectively. Conversely, weak acids and bases only partially ionize, resulting in lower concentrations of ions. pH measurement provides a quantitative indication of acidity or basicity, with lower pH values indicating stronger acids and higher values indicating stronger bases. Additionally, the extent of ionization can be assessed through acid dissociation constants (Ka) for acids or base dissociation constants (Kb) for bases.
