What is the general guideline for the prediction of solubility?
There is no ONE general guideline for predicting solubility. There are, however, a list of rules which can be consulted to predict the solubility of most compounds. One example of these rules can be found at the Chemwiki site.
What happens to the solubility of salts when temperature is lowered or raised?
When temperature is lowered, the solubility of most salts decreases because the solubility of solids generally decreases with decreasing temperature. Conversely, when temperature is raised, the solubility of most salts increases as the solubility of solids typically increases with increasing temperature.
Do all salts hae the same solubility?
No, the solubility of salts can vary based on their chemical composition and structure. Factors such as temperature, pressure, and the presence of other substances can also influence the solubility of salts.
How does temperature affect solubility of salts?
Increasing the temperature the solubilty of salts in water is higher.
What are the general solubility rules for CrO4 -2?
The chromate ion (CrO4^2-) generally follows these solubility rules: it is soluble in alkaline solutions and forms soluble compounds with alkali metals (like sodium and potassium) and ammonium ions (NH4+). However, chromates are generally insoluble with transition metals such as lead (Pb), barium (Ba), and calcium (Ca), which form insoluble chromate salts. Additionally, the solubility of chromates can be affected by the pH of the solution, as they tend to precipitate as insoluble forms in acidic conditions.
Tells which compounds are soluble insoluble or slightly soluble?

When dissolved salts?
Salts can be soluble or insoluble. The solubility depends principally on solvent, temperature, pressure rtc.
Do all salt crystals have the same solubility?
no all the salts have different solubility depending upon their extent of ionization
2Using the solubility rules predict whether the following compound would be soluble or not soluble potassium flouride A Soluble B not soluble?
Potassium fluoride (KF) is soluble in water according to solubility rules because all compounds containing alkali metal cations (such as potassium) are soluble in water, and fluoride salts are also generally soluble. Therefore, potassium fluoride is soluble.
If you were to raise the temperature of the solvent could the concentration levels of the solution increase?
Solubility of any solvent is usually temperature dependent and yes, the solubility of most salts increase when the temperature is increased. However the solubility of some salts also decreases with increasing temperature.
How do you determine the solubility of sparingly soluble salts?
The solubility of sparingly soluble salts can be determined by conducting a saturation test, in which excess solid salt is added to a solvent and the mixture is stirred until no more salt dissolves. The concentration of the dissolved salt at this point represents the solubility of the salt in that particular solvent at a given temperature. This value can be further verified by calculating the solubility product constant (Ksp) for the salt.
What are the 3 properties of salts?
Examples: water solubility, pH of the solution, density.
