Silver Iodate Solubility

Silver iodate is a sparingly soluble salt, which means that it dissolves only to a limited extent in water. Its solubility in water depends on a variety of factors such as temperature, pH, and the presence of other ions.

At room temperature, silver iodate has a solubility of about 0.014 grams per 100 milliliters of water, which is quite low. As the temperature increases, the solubility of silver iodate also increases, but only slightly. For example, at 100 degrees Celsius, its solubility increases to about 0.042 grams per 100 milliliters of water.

The solubility of silver iodate is also affected by the pH of the solution. At neutral or slightly acidic pH values, the solubility is relatively low. However, at higher pH values, the solubility increases significantly. This is because silver iodate is an acidic salt, meaning that it can react with water to form ions. In a basic solution, these ions are stabilized, making the salt more soluble.

Finally, the presence of other ions in the solution can also affect the solubility of silver iodate. For example, the presence of chloride ions can decrease the solubility of silver iodate by forming silver chloride, which is even less soluble than silver iodate. On the other hand, the presence of nitrate ions can increase the solubility of silver iodate by forming a complex ion with the silver ion.

Overall, the solubility of silver iodate is relatively low, but it can be influenced by a variety of factors such as temperature, pH, and the presence of other ions.
