Question

in my text book it says that if the calculated value is less than or equal to 0.1 then the color of the conjugate base (In- in this case) predominates. does this mean that the solution will be yellow then?

Answer 1

yes, yellow

Answer 2

In my text, it says FOR AN ACID INDICATOR, HIn, that if (HIn)/(In^-) = or> 10, the acid color predominates or if (HIn)/(In) <or= 0.1, the base color predominates. Make sure you are reading about acid indicator (versus base indicators) and that the ratio is as I have it above. The problem states that it is an acid indicator, I think, and that it dissociates into H3O^+ and In^- in the ionized form.

Answer 3

you are right....I wrote it wrong. Does this mean that the solution will be more toward the redish side?

Answer 4

Yes, I think red.
