Text Solution

AI Generated Solution

To classify Sodium chloride (NaCl), Iron (Fe), concentrated sulfuric acid (H₂SO₄), and sodium carbonate crystals (Na₂CO₃·10H₂O) based on their behavior when exposed to the atmosphere, we can analyze each substance step by step. ### Step-by-Step Solution: 1. **Sodium Chloride (NaCl)**: - When NaCl is exposed to the atmosphere, it does not react with air or absorb moisture. - **Observation**: There is **no change in mass**. - **Classification**: No change in mass. ...

Lowering in vapour pressure is determined by Ostwald and Walker dynamic methed. It is based on the prinicipal , that when air is allowed to pass through a solvent or solution, it takes up solventvapour with it to get itself saturated at that temperature I and II are weighted separately before and after passing dry air. Loss in mass of each set, gives the lowing of vapour pressure. The temperature of air, the solution and the solvent is kept constant. Gain in mass of anhydrous CaCl_(2) is proportional to :
