Which one of the following can be used as an acid base indicator by a visually impaired student?

Discuss the important theories of acid-base indicators.

Discuss the various types of acid-base titrations using indicators.

Which of halogen acids indicated below is incorrect ?

The rapid change of pH near the stoichiometric point of an acid-base titration is the basic of indicator detection. pH of the solution is related to the ratio of the concentration of conjugate acid (Hin) and base (In^(-)) forms of the indicator by the expression

Common indicator organism of water pollution is

State the colour change in a universal indicator e.g. pH paper on (i) slightly acidic soil (ii) slightly alkaline soil (iii) dairy milk (iv) human blood tested for medical diagonsis

The age pyramid with broad base indicates
