What are the four Hume-Rothery rules for the solid solubility of one element in another?
Ayume90
- If a solute differs in its atomic size by more than about 15% from the host, then it is likely to have a low solubility in that metal. The size factor is said to be unfavourable.
- If a solute has a large difference in electronegativity (or electropositivity) when compared with the host, then it is more likely to form a compound. Its solibility in the host would therefore be limited.
- A metal with a lower valency is more likely to dissolve in one which has a higher valency, than vice versa.

What happens to the solubility of oxygen in a pond as the pond decreases temperature?
Oxygen solubility in water is strange and does not follow "normal" solubility rules along with many other gases. The solubility increases as temperature decreases.
Tells which compounds are soluble insoluble or slightly soluble?
solubility table
2Using the solubility rules predict whether the following compound would be soluble or not soluble potassium flouride A Soluble B not soluble?
The solubility rules predict weather the compound soluble. This is what tells the weather.
To determine which of the products and precipitation reaction is the precipitate which of the following should you follow?
(Apex) solubility rules
2Using the solubility rules predict whether the following compound would be soluble or not soluble lead 2 sulfide A Soluble B not soluble?
Solubility predicts whether the compound will be soluble. This is taught in science.
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 chemistry principle governs the precipitation reaction?
Solubility Rules
How do i know when a formula is soluble?
You can determine whether a formula is soluble by referencing solubility rules. These rules provide guidelines on how different ions combine and react with each other in solution. If a combination of ions in a formula follows the solubility rules, then the formula is soluble. If it violates the solubility rules, the formula is insoluble.

Why is a solid moved along by a gas?
This is due to capillary action and the rules of solubility and polarity.

What determines the soluibility of a substance?
materials: 1) in case of solid solutions of replacement the solubility is determined by Hume-Rothery rules: a. the diameter of the replacement atom (B) must not differ more than 15% of the parental atom (A) b. they must have the same electrons at the valence shell. If B's valence is more than A's, then the solubility of B in A is more than the solubility of A in B. c. as the difference of elecrtonegativities is bigger the bond between A and B will be less metallic. Thus, S, Se, Te have small solubility in most metalls d. to have full solubility the number of the electrons per elemental cube, with acme a, ( electronic concentration) must be e/a<1.4 2) in case of solid solutions of insertion the solubility is determined by Hagg rules: a. the diameter of the insertion atom B must be smaller than the half diameter of the parental atom A b. A must be a transient element
When CaCl2 mixes with NaF what is the formula of the precipitate?
NaCl + CaF2 Check solubility rules to see if it even forms a precipate
