What is the role of ions in the solubility of partially soluble compounds?

In summary, the conversation discusses the solubility of a compound, specifically Pb(C2H3O2)2, which is classified as partially soluble in water. The concept of net ionic equations is also mentioned, with the understanding that not all of the compound will dissolve. The solubility of a compound does not necessarily determine its ionization. It is noted that the equilibrium lies on the left, which can be represented with an arrow pointing left.

Do you break up a partially soluble compound into ions in a net ionic equation? or do you just leave it as a molecule?

Not sure if I know what you mean by partial solubility.

in the solubility rules it says that Pb(C2H3O2)2 is partially soluble in water.

OK, for me that means weakly soluble - don't worry about that, English is my second language (or third, to be precise :wink: ).

Net ionic equation is identical, just the equilirbium lies on the left - that is, not everything dissolves.

Solubility doesn't say anything about ionization. Something weakly (sparingly, slightly, partially) soluble can also be weakly (sparingly, slightly, partially) ionized.

solubility of ionic compounds is in fact breaking the compounds up into their individual ions, but like borek said, the equilibrium lies on the left, which you can represent with an arrow that looks like this http://www.coolschool.ca/lor/CH12/common_files/equilibrium_arrow.gif [Broken] and just have the part pointing left be longer than the part pointing right

1. What are partially soluble compounds?

Partially soluble compounds are substances that can dissolve in certain solvents, but only to a limited extent. This means that some of the compound will dissolve, but there will still be some remaining undissolved particles in the solution.

2. How do partially soluble compounds differ from insoluble compounds?

Partially soluble compounds differ from insoluble compounds in that they are able to dissolve to some extent, whereas insoluble compounds do not dissolve at all. Insoluble compounds will remain as solid particles in the solvent, while partially soluble compounds will have some dissolved particles in the solution.

3. What factors can affect the solubility of partially soluble compounds?

The solubility of partially soluble compounds can be affected by factors such as temperature, pressure, and the nature of the solvent and the compound itself. For example, increasing the temperature can increase the solubility of some compounds, while decreasing the temperature can decrease their solubility.

4. How can we determine the solubility of a partially soluble compound?

The solubility of a partially soluble compound can be determined through experiments where the compound is added to various solvents and the amount of compound that dissolves is measured. This can also be done by consulting solubility tables or using mathematical models to predict solubility based on the compound's properties.

5. What are some common examples of partially soluble compounds?

Some common examples of partially soluble compounds include calcium carbonate (which is partially soluble in water), benzoic acid (which is partially soluble in ethanol), and copper(II) sulfate (which is partially soluble in water). These compounds have varying degrees of solubility in different solvents.
