ncert.nic.in(Bronsted-Lowry base) Fig. 6.2 : Structures of Methyl orange Choice of Indicator In the titration of strong acid and a weak base, methyl orange is chosen as indicator. When titration between strong base and weak acid is to be performed then phenolphthalein is a good indicator. In this case alkali is dropped from the burette and acid is taken in

crab.rutgers.eduBronsted-Lowry Lewis Arrhenius Definition (pre-1900) An acid is a substance that dissociates in water to give H 3 O+ ions. (Stronger acids like H 2 SO 4 were assumed to dissociate more than weaker acids like CH 3 CO 2 H). A base is a substance that dissociates in water to give …
