WebbIn strong acid - strong base titrations, the pH changes from 4 to 10 at the end-point so a suitable indicator must change colour within this range Methyl red and phenolphthalein are suitable indicators for these titrations Methyl orange is not ideal but it shows a significant enough colour change at the end point so is widely used WebbThe digits of pH that are before the decimal point are orders of magnitude (constant), so there are only two sig figs present after the decimal point. Only the units after the decimal point count for sig figs. ex: pH=9.25 9=order of magnitude .25=2 sig figs. ( 2 votes) Daniel 6 years ago At 6:59 Sal mentions how the reaction goes to completion.
