According to the Solubility Guidelines chemistry reference table, the salt that is least soluble in water among the options provided is:

a- PbCl2

To determine which of these salts is least soluble in water, you can refer to the Solubility Guidelines Chemistry Reference Table. Here's how you can find the answer:

1. Open your preferred search engine and search for "Solubility Guidelines Chemistry Reference Table."
2. Click on a reputable source that provides access to the Solubility Guidelines table.
3. Once you have the table in front of you, locate the given salts: PbCl2, RbCl, LiCl, and FeCl2.

Using the table, you will find information about the solubility of various salts in water. The table typically provides categories such as "Soluble," "Slightly Soluble," and "Insoluble." The least soluble salt in water will fall under the "Insoluble" category or have the lowest solubility value.

Please note that the solubility of salts can vary depending on factors such as temperature and concentration, so make sure to consider the conditions specified in the table.

By following these steps, you can find the answer to your question and determine which of the given salts is least soluble in water according to the Solubility Guidelines Chemistry Reference Table.
