• A. Distillation is used for the chloroform - aniline (IV).This method lowers the boiling point of liquids by reducing pressure, allowing separation of heat-sensitive compounds without decomposition.
• B. Fractional distillation is utilized for the separation of crude oil fractions (III). It involves a fractionating column that separates various components of crude oil based on their differing boiling points.
• C. Steam distillation is effective for separating aniline - water mixtures (II). This technique uses steam to separate substances with high boiling points or compounds immiscible with water.
• D. Distillation under reduced pressure is applied for separation of glycerol from spent-lye (I). Distillation works by heating the mixture to evaporate the component with a lower boiling point and condensing it in a separate chamber, useful for separating components in solutions.
Brass alloy is made of which metals?
Electrolysis of 600 mL aqueous solution of NaCl for 5 min changes the pH of the solution to 12. The current in Amperes used for the given electrolysis is ….. (Nearest integer).
If the system of equations \[ x + 2y - 3z = 2, \quad 2x + \lambda y + 5z = 5, \quad 14x + 3y + \mu z = 33 \] has infinitely many solutions, then \( \lambda + \mu \) is equal to:}
