When some compounds dissolve, the process is exothermic because the energy released during the formation of interactions between solute and solvent molecules exceeds the energy required to break the solute's bonds. This release of energy often occurs when strong attractions, such as hydrogen bonds or ion-dipole interactions, are formed. As a result, the overall energy change is negative, indicating that heat is released into the surroundings, leading to an increase in temperature. Thus, the exothermic nature of dissolution is linked to the balance of energy changes during the process.

How can water dissolve some ionic compounds as well as some molecular compounds?

Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.


The process by which some molecular compounds dissolve in water to form ions is?

The process by which some molecular compounds dissolve in water to form ions is called dissolution or ionization. This occurs when the polar water molecules surround and separate the individual ions in the compound, breaking the bonds holding them together. This results in the compound dissociating into its constituent ions.


Are all ionic compounds that dissolve electrolytes?

Not all ionic compounds dissolve into electrolytes. Only ionic compounds that dissociate into ions in solution and conduct electricity are considered electrolytes. Some ionic compounds do not dissolve well in water and consequently do not conduct electricity.


Is heat often given off when compounds are formed?

yes heat is given of due to the exothermic process in some cases. e.g when caco3 is mixed with water heat is given of.


Is zirconium exothermic?

Zirconium is not itself explosive, but it is used in making alloys used in explosive primers because of its resistance to corrosion. It is flammable, particularly in powder form, and is sometimes used in incendiary bombs for this reason.


What compounds that do not dissolve in water are usually found in everyday household items?

Nonpolar compounds that do not dissolve in water are commonly found in everyday household items. Examples include fats, oils, waxes, and some plastics.


Some covalent compound dissociate dissociate into ions when they dissolve in water and what atom do these compounds have in their structure?

oxygen


Does water only dissolve inorganic compounds?

No, water can dissolve both inorganic and organic compounds. Water is considered a universal solvent because it has the ability to dissolve a wide variety of substances due to its polar nature and ability to form hydrogen bonds.


What type of compounds dissolve best in cold water?

some of the tertiary amines are best soluble in cold water


Is it true or false that water can dissolve anything that is why it is called the universal solvent?

While water is known as the universal solvent because of its ability to dissolve many substances, it cannot dissolve everything. Water can dissolve polar or ionic compounds due to its polarity, but it may struggle to dissolve non-polar substances like oils and fats. Some compounds, like certain metals or plastics, are not easily dissolved by water.


Does Greenium dissolve in water?

Greenium is a fictional substance and does not exist in reality. However, if we assume that Greenium is similar to other compounds, its solubility in water would depend on its chemical structure. Some compounds dissolve in water, while others may not.


Why don't some covalent compounds dissolve in water?

Some covalent compounds do not dissolve in water because they may lack polar groups or have strong intermolecular forces that make them incompatible with water molecules. Water is a polar solvent, so for a covalent compound to dissolve in water, it often needs to have polar or ionic characteristics for effective interactions with water molecules.
