The question says that there is an indicator which is red when undissociated and yellow when dissociated, and asks for the color of it when it is in a strong acidic environment.
My thought is that the indicator can be both a weak base or a weak acid. A weak acid will be undissociated at low pH, while a weak base will be dissociated. Thus whether the indicator is dissociated will depends on the nature, i.e. whether it's a base or an acid.
However, the answer says it should be red, hence undissociated, regardless whether it is base/acid.
Can anyone help?
Thanks a lot!
Just want to add another quick question regarding valence electron and quantum number: Which set of quantum numbers best describe a valence electron in Germanium?
The correct answer is 4,1,1,1/2. But shouldn't 4,0,0,1/2, which describe a 4s electron, also be a valid answer?
Thanks again!
