In the first step, since we are adding a concentrated acid, it will react with the bases present in the mixture (diethylamine and ammonia) forming salts, which are soluble in water. Therefore, after draining the aqueous layer, we will have phenol and acetic acid left in the organic layer.

In the second step, we are adding a diluted base, so it will react with a strong acid. This compound is acetic acid, and its salt will be present in the aqueous layer. Phenol will be left on the organic layer.

A student analyzed an antacid tablet from a bottle containing 120 tablets purchased for $2.79. The mass of the tablet was 1.247

BaLLatris [955]

The cost of one antacid is 2.325 cents per tablet.

Explanation:

As per the question based on the student analysis we know that,

Total antacid tablets in a bottle = 120

Purchase Price of a bottle = $ 2.79

Cost of 1 antacid tablet $=\frac{2.79}{120}$

As we know $1 = 100 cent

The cost of 1 antacid tablet = $\frac{2.79}{120}$ × 100 cents = 2.325 cents/tablet .

Thus we came to know that it costs 2.325 cents/tablet .
