The solubility of silicon dioxide, SiO2, in water depends on a number of different factors, including pressure, temperature and the structure of its surface. Generally speaking, silicon dioxide is virtually insoluble in water at room temperature.Know More
The solubility of silicon dioxide increases with higher pressure or temperatures, with the level of solubility increasing dramatically above 100 degrees Fahrenheit. When silicon dioxide dissolves in water, the reaction forms silicilic acid.
There are more than 13 distinct structural modifications of silicon dioxide, each of which has its own level of solubility. For instance, macrocrystalline quartz is much less soluble than either chalcedony or amorphous quartz glass.Learn more about Solutions & Mixtures
According to Aqueous Solutions Aps, K2SO4 is soluble in water at different temperatures. Potassium sulfate (K2SO4) is, however, salted out when mixed with water and other solvents, which means an excess of salt precipitates and solubility decreases.Full Answer >
The compound NaC2H3O2, which is commonly called sodium acetate, is soluble in water. At 32 degrees Fahrenheit, 100 milliliters of water dissolve 119 grams of sodium acetate. At 212 degrees Fahrenheit, the same amount of water dissolves approximately 170 grams of sodium acetate.Full Answer >
Pb(NO3)2 is soluble in water. Pb(NO3)2 is the formula of lead(II) nitrate, an inorganic compound whose water solubility is 52 grams per 100 milliliters at 20 degrees Celsius and 127 grams per 100 milliliters at 100 degrees Celsius.Full Answer >
Ethanol is soluble in water because the polarity of its hydroxyl group is stronger than the nonpolarity of its two carbon chain. In alcohols with more than five carbons in their chain, the repulsive forces between the nonpolar chain and polar water do not allow the two to mix, according to Solubility of Things.Full Answer >
