Question

Physical Properties: Water Vegetable oil aqueous NaOH solution Sodium hydroxide ethanol Soap glycerol Saturated Nacl

Answer 1

Physical properties :

1. water : Water is a tasteless, odorless liquid at ambient temperature and pressure, and appears colorless in small quantities, although it has its own intrinsic very light blue hue.Ice also appears colorless, and water vapor is essentially invisible as a gas. Water is primarily a liquid under standard conditions. Boiling point 100oC and freezing point 0oC.

2. vegetable oil : High density, high viscosity , liquid at room temperature. High boilng point and melting point.

3.aqueous NaOH solution : Same as water. Basic is nature , turns red litmus to blue

4. Sodium hydrolxide : solid, hygroscopic in nature.
