write a net ionic equation for the reaction of each weak acid form of these indicators with water:
A) Bromothymol blue
B)Congo Red, HCr(aq)
C)Methyl orange

what are the formulas of A,C
 also can someone pls show me an example so i can see if im doign it right

Dear Mckelvie;

The Formulas you can find on Wikipedia; and the members of the “Board” will be so kind to check your tries.

Good Luck!

is it just:
A) C27H28Br2O2S + HOH <--> C27H27Br2O5S +H30
B)HCr + HOH <---> Cr +H3O
C)C14H14N3NaO3S + HOH < ----> C14H13N3NaO3S +H3O

or is it somethign crazy like
A) C27H28Br2O2S + 27HOH <--> C27Br205S +27 H30
B)HCr + HOH <---> Cr +H3O
c)C14H14N3NaO3S +14 HOH < ----> C14N3NaO3S +14H3O
or is Mckelvie just insane

Dear Mckelvie;

Not exactly!,    ─    I’m missing the Charges and so on.

At least for “Bromothymol Blue” you can find the whole Equation on Wiki too!
(In the first paragraph.)

Let’s have another try.

Good Luck!

nvm

[Mckelvie]

i know what to do now, i never seen soem info that was on my sheet

Dear Mckelvie;

I can’t believe that you visited Wiki!,   ─   

Because otherwise you would have found for “Bromothymol Blue”:

     C27H28Br2O5S      <------->     H⁺    +   C27H27Br2O5S⁻

What do you think?

Good Luck!
