Which is more soluble in water, Cl2 or I2?
I looked them up on Google. Cl2 is more soluble. At 20 C Cl2 is about 7 g/kg water. For I2 about 1 g/3.5 kg water.
Thank you @DrBob222
To determine which substance is more soluble in water, we need to consider their properties and the nature of their interaction with water molecules.
In the case of Cl2 (chlorine gas) and I2 (iodine), both substances consist of nonpolar molecules. Nonpolar substances have weak interactions with water because they lack an electric charge that allows them to form hydrogen bonds with water molecules.
However, despite being nonpolar, iodine (I2) is more soluble in water compared to chlorine (Cl2) due to its larger molecular size. As the molecular size increases, so does the van der Waals forces between the molecules. These forces can contribute to the solubility of a substance in water.
To verify this information, we can consult reliable sources such as chemical databases, textbooks, or experimental data. Additionally, conducting experiments to measure the solubility of Cl2 and I2 in water under controlled conditions can provide more accurate and quantitative data.
