3) (2 points) The phenolic indicator (In-OH) has approximately the same pKa as a carboxylic acid. Which H is the most acidic pro
ton in In-OH
1 answer:
Explanation:
In a phenolic indicator, the hydrogen atom is attached to more electronegative atom which is oxygen atom (O atom). So, when a phenolic indicator loses a proton then a conjugate base is formed.
This conjugate base is much more stable due to the resonance stabilization.
Therefore, we can conclude that proton attached to oxygen atom is much more stabilized than any other protons in a phenolic indicator.

C:
Explanation:
we can use the molarity equation
so to find M we plug in what we know, which is 6 moles of NaCl and 2 L of water, which gives us:
