Going Across:
Weak Strong Basic >7 Phenolphthalein
Strong Weak Acidic <7 Methyl Orange
HCl NaOH (Strong Strong) 7 Bromothymol Blue

note that for the last one in theory we say bromothymol blue since it has a color change at the end point however the titration curve for a strong-strong titration has a steep inflexion point and so we can use any of the three indicators in the syllabus so practically we would use phenolpthalein, becuase it has a more distinct color change
