The partition coefficient of iodine between carbon tetrachloride (CCl4) and water (H2O) is a measure of how much iodine prefers to dissolve in CCl4 compared to H2O. It is denoted by K and is calculated as:

K = [I2](CCl4) / [I2](H2O)

Where:

* [I2](CCl4) is the concentration of iodine in carbon tetrachloride

* [I2](H2O) is the concentration of iodine in water

The partition coefficient for iodine between CCl4 and H2O is approximately 85. This means that iodine is 85 times more soluble in CCl4 than in water.

Important Note:

* This value is an approximate value and can vary slightly depending on temperature and other experimental conditions.

* The partition coefficient is a useful tool for understanding the distribution of a substance between two immiscible phases, which is essential for various applications like extraction and purification.
