its because an indicator is suitable only if it undergoes a change of colour at the pH near the end point. Thus the indicators like methyl orange, methyl red and phenolphthalein can show the colour change in the ph range of 4t0 10. Thus, in strong acid- strong base titrations, any one of the above indicators can be used.
