pls arrange the following in their order of solubility: NH3, N2 AND CO2

arange the gases in the increasing order of solubility in water.NH3;N2;CO2

Look up charts at the following link.

For reference, use solubility at 20° in terms of g/kg.H2O.
NH3 leads the list at 520 g/kg.H2O.

N2,CO2,NH3

To determine the order of solubility of these compounds, we need to consider their intermolecular forces and molecular structures.

1. NH3 (Ammonia):
Ammonia is a polar compound with a bent molecular structure. It exhibits hydrogen bonding with water molecules. Hydrogen bonding increases solubility in water. Hence, NH3 is highly soluble in water.

Order of solubility: NH3 > N2 > CO2

2. N2 (Nitrogen gas):
Nitrogen gas, N2, is a nonpolar molecule consisting of two nitrogen atoms bonded by a triple bond. Nonpolar molecules do not readily interact with water molecules, resulting in low solubility. Therefore, N2 is relatively insoluble in water.

Order of solubility: NH3 > CO2 > N2

3. CO2 (Carbon dioxide):
Carbon dioxide is a polar molecule with a linear structure. It exhibits weak London dispersion forces. Although CO2 can undergo limited solvation in water due to its polarity, it is not as soluble as NH3. However, it is more soluble than N2 due to the presence of polar covalent bonds.

Order of solubility: NH3 > CO2 > N2

In summary, NH3 (Ammonia) is the most soluble, followed by CO2 (Carbon dioxide), and N2 (Nitrogen gas) is the least soluble among these compounds in water.
