Did old breathalysers make ethanol turn into an aldehyde or carboxylic acid?

As above!! Reaction causes a colour change of orange to green but was an aldehyde or carboxylic acid made?

Does it matter?

The colour change shows that there is an oxidisable compound in that person's breath, i.e. EtOH.

Who care's what forms?

Pigster is right! You are only seeing a color-change because of the change in the oxidation state of Cr3+.

I suspect you would form the aldehyde mostly, it's possible there would be some acid-forming if there was excess oxidising agent.
