The most soluble salt? Is copper sulfate pentahydrate soluble in water
The most soluble salt? Is copper sulfate pentahydrate soluble in water?
In the chemical industry, the solubility of salt is an important property, because it directly affects the application scenarios and industrial preparation process of salt. Among the many salts, some are known for their extremely high solubility and are called "the most soluble salts". This article will discuss which salts belong to this category, and focus on the analysis of whether copper sulfate pentahydrate is soluble in water, and its dissolution characteristics.
What is the "most soluble salt"?
In the field of chemistry, the solubility of a salt usually refers to the maximum amount of a salt that can be dissolved in 100 grams of water at a specific temperature. Salts with high solubility are referred to as "readily soluble salts". Among the many salts, sodium chloride (NaCl), potassium nitrate (KNO3) and ammonium sulfate ((NH4)2SO4) are recognized as soluble salts.
1. Sodium chloride (NaCl): one of the most soluble salts
Sodium chloride, or table salt, is one of the most common salts in nature. At 25°C, the solubility of sodium chloride in water is about 36g/100g water. Although this value is not particularly high, it is widely used in industry and life, so it is often considered to be one of the representatives of soluble salts. The dissolution process of sodium chloride is mainly due to its ionic structure, Na + and Cl-ions dissociate and disperse uniformly in water.
2. Potassium nitrate (KNO3): high solubility salt
Potassium nitrate is an inorganic salt whose solubility is about 32g/100g water at 25°C, and the solubility increases significantly with increasing temperature. Because of its high solubility and good water solubility, potassium nitrate is widely used in agricultural fertilizer and gunpowder manufacturing. The dissolution process of potassium nitrate involves the dissociation of K + and NO3-ions, which makes it have high conductivity in solution.
3. Ammonium sulfate
