why do only some salts dissolve? are there any rules which tell you which will?
Answers
Answer:
Explanation:
When a salt such as sodium chloride (table salt) dissolves in water, its ionic lattice is pulled apart so that the individual sodium and chloride ions go into solution. In practice, many salts that are described as insoluble do actually ionize slightly in water, releasing ions into solution.
Most silver salts are insoluble. AgNO3 and Ag(C2H3O2) are common soluble salts of silver; virtually all others are insoluble.
Most sulfate salts are soluble. Important exceptions to this rule include CaSO4, BaSO4, PbSO4, Ag2SO4 and SrSO4 .
Most hydroxide salts are only slightly soluble. Hydroxide salts of Group I elements are soluble. Hydroxide salts of Group II elements (Ca, Sr, and Ba) are slightly soluble. Hydroxide salts of transition metals and Al3+ are insoluble. Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble.
Some salts dissolve in water but many others salts do not dissolve easily.
Explanation:
Charges on the ions of the salt decide the solubility of salts.
Highly charged ions interact with each other.
They are strongly interacting with water molecules.
when a salt dissolves in water the sodium ion and chloride ions go into the solution and are pulled from the lattice.
Many salts are insoluble because they ionize slowly in water releasing the ions in the solution.
Water molecules attract the positively charged sodium ions and negatively charged chloride ions both.
Most silver salts are not soluble in water.
Hydroxide salts are slightly soluble in water.
