Which statement is FALSE for indicators? Indicators are chosen to change color as close to the end point as possible. The volume difference between the equivalence point and the end point is indicator error. The pH range over which an indicator changes color is the transition range Indicators are acids or bases whose various protonated forms have different colors. Indicators can change color more than once.

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
