Soluble substances are those substances that are easily dissolved, usually in water . Examples of these are sugar, salt, ethanol, powdered juice, dishwashing detergent, coffee, chocolate, sodium bicarbonate, potassium carbonate and calcium bromide.

If solubility is a propety of a substance explain why some substance will dissolve in some substasnce but no others?
because the solubility is a propety of a substance and some substance will dissolve in some substasnce but no others
Why are solubility tests helpful to determine unknown substances?
A simple solubility test can be used to identify an unknown substance. Most substance will make a precipitate when around certain molecules.
What is meant by the term soluble?
It means that some substance is capable of being dissolved in liquid - possibly only in certain liquids.
How does solubility depends on temperature?
No. When dissolving a solid into a liquid, solubility is higher when the temperature is higher. When dissolving a gas into a liquid, solubility is higher when the temperature is lower.
What is mean by the solibility of a substance?
If you mean solubility, it refers to the ability for the substance to dissolve in water (or ethanol). It tells you how much of the solid is able to dissolve under RTP (room temperature and pressure). I am not too sure what it is useful for (maybe crystallization of some sorts but that's what I can tell).
Does the solubility increase as the temperature increases?
Perhaps you mean the solubility of substances in water. Most solids have increasing solubility in water with increase in temperature, but certainly not all of them. Some solids e.g. Cerium Sulphate have decreased solubility in water at higher temperatures, while some solids show increasing solubility up to a certain temperature, above which the solubility decreases, such as Sodium Sulphate. The solubility of common salt, Sodium Chloride, is almost unaffected by temperature. Gases generally have lower solubility in water at higher temperatures.
Solubility can be increased by what?
Gas is more soluble in a liquid at lower temperatures. This is quite understandable, because heat tends to make a gas expand, and the process of expansion will cause some gas to leave the liquid which will no longer be large enough to contain it.
How can solubility be changed?
by heating or cooling the water... i think, im in 8th grade IPS so trust my answer if you want. i wouldn't, i barely ever pay attention in class anyway. But aside from all that im 90% sure that's right.
What is solubility curves?
It is a curve solubility (in grams of solute to 100 g watere) versus temperature. See at the link below some examples.
What physical property identify a substance?
There are many varying physical properties used to identify a pure substance. Some of the most prevalent physical properties are color, odor, density, melting and freezing points and solubility.
How can solubility be affected?
Factors affeccting the solubilty are:1. the nature of solute/solvent (chemical composition, polarity)2. temperature3. pressure4. stirring5. surface area of the solute6. some added compounds7. amount of the solute 8. the geometry of the beaker
Solubility is dependent on what two things?
Solubility is the property of a solid/liquid/gaseous chemical substance called the solute, to dissolve in a solvent thus forming a homogeneous solution. Generally the solvent is a liquid. Solubility of a substance fundamentally depends on the solvent used, the temperature and pressure. Solubility does not depend on particle size or other kinetic factors; given enough time, even large particles will eventually dissolve.NOTE: The term 'solubility' is not applicable for solutions that are formed all/partially via chemical reaction. That process is known as liquefaction or chemical dissolution.The amount of solubility varies widely: fromtotally soluble (fully miscible -- that is soluble in any/all proportions)to insoluble (unable to form a homogeneous solution).
