Cations don't always form soluble compounds. In general, ionic compounds are soluble in very polar solvents such as water and insoluble in nonpolar solvents because the charged ions can be solvated only by polar solvents. Some ionic compounds are insoluble even in water, however.

Which anion forms soluble compounds?
Anions such as acetate (C2H3O2-), chloride (Cl-), nitrate (NO3-), and sulfate (SO4^2-) typically form soluble compounds with most cations. However, there are exceptions based on specific compounds and conditions.
What type of compound does cations and anions compose?
Cations and anions combine to form ionic compounds through the attraction between opposite charges. In an ionic compound, the cations and anions are held together by electrostatic forces.
Are nitrate ions soluble?
Yes, nitrate ions (NO3-) are highly soluble in water. They are considered to be fully soluble because they do not form precipitates with common cations.
What compound that forms ions in solution?
Ionic compounds are substances that form ions in solution. These compounds are composed of positively charged cations and negatively charged anions that dissociate in water to form free ions. Examples include table salt (sodium chloride, NaCl) and calcium carbonate (CaCO3).
Ionic compounds are always what?
Ionic compounds are always composed of positively charged cations and negatively charged anions held together by electrostatic forces. They typically form crystalline structures and have high melting and boiling points due to their strong ionic bonds.

Does Na plus and NO3- form a soluble compound?
Yes, sodium compounds are soluble.
What is sodium and calcium in form ionic compounds?
Sodium and calcium form the cations Na+ and Ca(2+).
Are nitrate ions soluble?
Yes, nitrate ions (NO3-) are highly soluble in water. They are considered to be fully soluble because they do not form precipitates with common cations.
What are ionic compounds called when they don't form precipitate?
Soluble
Is silver phosphate more soluble than sodium phosphate?
No - sodium is a group 1 cation and group 1 cations are nearly always soluble. By contrast, the silver cation is very likely to form a precipitate. Source - AP Chem student
What type of compound does not have cations or anions?
Compounds with covalent bonds form molecules not ions Compounds consisting of non-metals bonded to nonmetals do not form ions

What cations does Cu form and what are their charges?
Cu2+ is more stable, though Cu+ compounds are known

Are cations or anions soluble in water?
In general, cations are soluble in water because they form positive ions that can attract the negatively charged oxygen atoms in water molecules. Anions can also be soluble in water depending on their size and charge, but some large and highly charged anions are less soluble due to stronger electrostatic interactions with water molecules.
