Do you break up a partially soluble compound into ions in a net ionic equation? or do you just leave it as a molecule?
What is the role of ions in the solubility of partially soluble compounds?

Discussion Overview
The discussion revolves around the role of ions in the solubility of partially soluble compounds, specifically focusing on how to represent these compounds in net ionic equations. Participants explore the implications of partial solubility and ionization in the context of ionic compounds.
Discussion Character
- Debate/contested
- Conceptual clarification
- Technical explanation
Main Points Raised
- One participant questions whether a partially soluble compound should be represented as a molecule or broken down into ions in a net ionic equation.
- Another participant expresses uncertainty about the term "partial solubility" and its implications.
- A participant cites solubility rules indicating that Pb(C2H3O2)2 is partially soluble in water.
- One participant interprets partial solubility as weak solubility and clarifies that the net ionic equation remains the same, but the equilibrium lies on the left, indicating incomplete dissolution.
- Another participant notes that solubility does not necessarily imply ionization, suggesting that a compound can be weakly soluble and weakly ionized simultaneously.
- A participant asserts that the solubility of ionic compounds involves breaking them into individual ions, but emphasizes that the equilibrium favors the undissolved state, which can be represented with a specific equilibrium arrow notation.
Areas of Agreement / Disagreement
Participants express differing views on the representation of partially soluble compounds in net ionic equations and the relationship between solubility and ionization. The discussion remains unresolved with multiple competing perspectives.
Contextual Notes
Participants have not fully defined "partial solubility," and there are varying interpretations of how it relates to ionization and equilibrium in net ionic equations.

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 
).
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 and just have the part pointing left be longer than the part pointing right
