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.
Answer:
An unsaturated solution.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to firstly realize we need to calculate the grams of vanillin in 0.070 moles by using its molar mass of 152.15 g/mol:
Thus, since the solubility is 10.65 g per 1 L of solution, we can notice 5.00 g will complete dissolve and produce an unsaturated solution.
Best regards!
