So let's say you have the indicator
Orange IV

and it's pH range which colour occurs is
1.4 - 2.8

and the colour change as pH increases
red to yellow


So my question is if the pH was 1.3 or 1.2 or 1...would the colour be red? Likewise, at 2.9 or 3, would the colour be yellow?

Also, if the pH is 2, is the colour something like...orange?


Argh! Chemistry books and teachers provide an inadequate amount of information on indicators...
