You prepare aniline in the lab via an aqueous synthesis. 50 mL of crude aniline is collected in this procedure. The crude product is purified via distillation, and you record a boiling point of 92°C. This temperature remained constant throughout most of the distillation. However, the distillate drips into the receiving flask as a cloudy liquid that separates into two layers as it cools. Completely explain these results and observations.

Explanation:

The distillation of aniline in which crude aniline is vaporized in presence of water to produce a mixture of aniline and steam. The vapors are condensed to liquid and the two liquids are separated by gravity separation. At elevated temperature, they are separated into two sharp layers. The water layer being heavier than aniline layer form inner layer, while aniline forms upper layer. The separation of aqueous aniline from water is becomes possible because aniline forms azeotropic mixture with water at  boiling point 98 C.

first one is the correct answer

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
