Titrating with an Acid-Base Indicator

Methyl red is a poor choice, however, because its color change, from 4.2 to 6.0, begins well before the equivalence point is reached. 

Is methyl red a suitable indicator when you are titrating a strong acid with a strong base Explain your answer. 

Suitable indicator for titration of a weak acid with a strong base because equivalence point falls within the color-change interval 

Why is the choice of indicator more crucial for a weak acid-strong base titration than for a strong acid-strong base titration  

The point in a titration where the indicator changes color is called the end point to distinguish it from the equivalence point that it closely approximates. 

Suitable indicator because equivalence point falls within the color-change interval 

Unsatisfactory indicator because color changes before reaching equivalence point
