Dissolution overall can be either endothermic or exothermic, depending on whether more energy was used to break the bonds, or more energy was released when new bonds were formed. If more energy is released in making bonds than is used in breaking bonds, the process is exothermic. If more energy is used than is released, the process is endothermic.
Examples include Urea [CO(NH2)2], Potassium Nitrate [KNO3] and Ammonium Nitrate [NH4NO3]. All are commonly found in "Instant cold packs" that become cold when you rupture the inner bag by depressing the pack gently but firmly. When then inner water makes contact with the chemicals listed above inside the outer bag of the pack, the endothermic reaction begins. This is the source of the cold temperature these types of Instant Cold Packs produce.
salt, when in water, dissolves exothermically, for instance when water is heated vapor is released making it exothermic. when salt is dissolved in water it also does this
Sodium Hydroxide dissolves in water exothermically. This is a very common base NaOH, It is also known as Caustic Soda.
Ammonium Nitrate is the name of a substance that dissolves endothermically
Ammonium nitrate
Sodium bicarbonate
Alkeseltzer in water
This substance is called solvent.
A solution.
Alcohol dissolves cinnamon in water.
This is a solution.
Sprite fizzes because it has gasses dissolves in the liquid. When the container is opened pressure releases allowing the gasses to escape.
A dangerous substance that dissolves other materials is acid. Acid can eat away at most metals and will burn the skin severely.
It exothermically reacts and dissolves
It reacts with acids, it dissolves exothermically in water to produce a basic solution.
An example of a compound that forms exothermically is hydrogen fluoride. It can exist as a colorless gas or as a fuming liquid, and can also be dissolved in water.
Calcium chloride can act as an irritant by desiccating moist skin. Solid calcium chloride dissolves exothermically, and burns can result in the mouth and esophagus if it is ingested. Ingestion of concentrated solutions or solid products may cause gastrointestinal irritation or ulceration
Hydrogen will, thus forming water. But there are probably more substances
The solvent dissolves the solute. (The solute dissolves in the solvent.)
The solvent dissolves the solute. (The solute dissolves in the solvent.)
it dissolves
Exothermic means it gives out heat or energy
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
The substance that dissolves is called the "solute" and the substance that the solute dissolves in is called the "solvent".
