An example of solubility is the fact that sugar is very soluble in water. However, in another liquid, such as methyl alcohol, it is only somewhat soluble.Know More
Solubility is defined as how much of a solute will dissolve in a particular amount of a solvent. Most solutes vary with different solvents. In the example used above, sugar was the solute and the solvents were methyl alcohol and water.
According to HowStuffWorks, solubility differs greatly depending on the state of matter, temperature and pressure. For example, most solids and liquids increase in solubility at higher temperatures, but in the same situation, gases decrease in solubility. Under pressure, though, gases become more soluble.
An example of this would be carbonated drinks. Drinks such as soda are bottled under pressure because gases are more soluble in this state. When the pressure is released by someone opening the container, the carbon dioxide instantly starts to lose its solubility and begins to escape.
Based on these properties, there are several examples of solubility. Salt, for instance, is soluble in water, but it isn't soluble in oil. It is possible to add both cream and sugar to coffee because both are soluble in the drink. Another example of solubility is in the air: oxygen is soluble in nitrogen.Learn more in Solutions & Mixtures
The solubility of elemental calcium in water is unassessable because calcium reacts with liquid water to produce calcium hydroxide in a hydrolysis reaction. The reaction produces hydrogen gas and calcium hydroxide as byproducts.Full Answer >
Increasing salinity decreases water solubility, such that the oceans can dissolve about 20 percent less oxygen than fresh water of the same temperature. Any other solutes in water tend to decrease the solubility of gases, particularly non-polar gases like oxygen. Temperature and pressure are the other major factors in solubility, with increases in temperature reducing gas solubility and increasing the solubility of most other solutes.Full Answer >
Sugar water freezes faster than salt water, because salt has more molecules than sugar. Normally, water freezes at 32°F, however, when a substance is added to the water, it lowers its freezing point. This is not because of the chemical nature of the substance being added, but rather the number of molecules. This is referred to as a colligative property.Full Answer >
The Department of Physics at the University of Illinois states that sugar dissolves faster in hot water than in cold water because hot water gives sugar crystals energy. The hotter the water, the higher the energy, and the faster sugar crystals dissolve.Full Answer >
