Answer:
No net change in reaction occurs in this nucleophilic acyl subtitution reaction
Explanation:
Sodium ethoxide in ethanol gives nucleophilic acyl substitution reaction with ethyl-2-methylpropanoate.
Here ethoxide group replaces an ethoxide group from ester through addition-ellimination pathway.
So, ultimately, the product of this reaction is identical with reactant i.e. ethyl-2-methylpropanoate is reproduced.
Hence one might observe no change during reaction as product and reactant of this reaction are same.
Mechanistic pathway has been shown below.
The concentration of hydroxide ion is 5 10^

<u>Explanation:</u>
Consider the equilibrium of this acid's dissociation,
H C l O 4 ⇌ H + + C l O 4 -
Moreover, let's assume that H C l O 4 is a strong acid and will fully dissociate.
Hence,
[ H + ] = 0.20 M
Now, recall,
