The mixture of phenol and benzoic acid is separated by adding to produce brisk effervescence with sodium benzoate .
When benzoic acid react with then sodium benzoate is produced which is soluble in water and separated from non aqueous solvent . Organic compounds are soluble in organic solvent and inorganic compound mainly soluble in inorganic solvent like water.
What is brisk effervescence?
Brisk effervescence is when continuous gas evolution occurs in a chemical reaction like CO2. When HCl is added in then CO2 evolved.

Answer:
38.8 mL
Explanation:
2CO(g) + O₂(g)⟶2CO₂(g)
Because pressure and temperature remain constant, we can <em>think of the moles ratios as volume ratios</em>. This means that 2mL of CO react with 1 mL of O₂ to produce 2 mL of CO₂.
Because the problem asks us to calculate the amount of oxygen gas unreacted, then CO is the limiting reactant. We <u>calculate the amount of O₂ that reacted</u>, from the available amount of CO:
82.4 mL CO * = 41.2 mL O₂
Thus, the oxygen gas remaining is:
80.0 mL - 41.2 mL = 38.8 mL O₂
