Silicon dioxide, the primary component in sand, forms in large crystalline structures, which are held together by covalent bonds. These bonds require more energy to break than the polarity of water is able to supply. While water is able to dissolve a minute amount of silicon dioxide, natural water supplies are at the saturation point and unable to dissolve any more sand.Know More
Silicon dioxide is the most abundant chemical compound in the earth's crust. It is the primary component of quartz, sandstone, opal, granite, clay and many rocks. It forms the skeletal parts of diatoms and sponges. In higher plants, the chemical forms stems and other tissues. It is relatively unreactive with most chemicals, including strong acids, with the exception of hydrofluoric acid, making silica glass a good choice for laboratory glassware.
According to About.com, sand is technically just a size category. It is a particulate matter larger than slit, yet smaller than gravel. Many scientists and geologists have different definitions for what sand is.
Dirty sand is quartz that mixes with other mineral grains of similar size. In certain locations, basalt lava weathers to create black sand. In others, olivine forms green sandy beaches. While these other types of sands include chemicals other than silicon dioxide, they are also relatively insoluble in water.Learn More
Vinegar does not dissolve in water. When an element or substance dissolves in water, it is considered soluble. Substances that do not dissolve are insoluble.Full Answer >
Methanol is highly soluble in water, therefore, large amounts of methanol can be dissolved in water. This high solubility is caused by the short hydrocarbon chain and the presence of a hydroxyl group.Full Answer >
Glucose dissolves in water because the strong magnetic charge of water is able to break the molecular bonds that connect the sugar molecules. Crystalline sugar consists of a matrix of molecules held together by relatively weak bonds, and when submerged in water, the stronger charge of the water molecules pulls the sugar apart.Full Answer >
Dissolving salt in water is an example of a chemical change. The dissolution leads the salt to break into sodium and chlorine ions, so it alters its essential chemical properties. Even though boiling salt water ends up leaving behind a residue of salt, while the salt and water are together, the chemical processes change enough to be viewed as a chemical reaction.Full Answer >
