hydration of the ions- this forms aqua complexes. The energy of formation of the aqua complexes has to be greater than the energy holding the crystal together. This is true for NaCl which is a soluble compound, but untrue for calcium chloride which has very low solubility.

What type of reaction can an element and compound be combined?
An element and a compound can undergo a chemical reaction called a single replacement reaction. In this type of reaction, the element replaces one of the elements in the compound, forming a new compound and a different element as a product.
What happens when mixing calcium nitrate in water compound?
When calcium nitrate is mixed in water, it dissociates into its ions: calcium (Ca2+) and nitrate (NO3-). These ions remain in solution and are free to interact with other substances present in the solution. The solution will also undergo an endothermic process as the dissolution of calcium nitrate in water absorbs heat from the surroundings.
What is the process of combining acids and bases to make salts and water?
When an acid reacts with a base, they undergo a neutralization reaction where they combine to form a salt and water. The acid donates a proton (H+) to the base, forming water, while the remaining ions combine to form a salt. This process typically results in a solution with a neutral pH.
What happens when you react 4-hydroxyacetophenone with Water HCl and?
When 4-hydroxyacetophenone reacts with water and HCl, it may undergo protonation of the oxygen atom in the hydroxyl group, leading to the formation of a hydroxyacetophenone-HCl salt. This process can enhance the solubility of the compound in aqueous solution.
Does magnetite react with acid?
Yes, magnetite (Fe3O4) does react with acid. When exposed to acid, magnetite can undergo dissolution, releasing iron ions into solution and forming iron salts.

What do igneous rocks that undergo weather and erosion become?
Igneous rocks that undergo weathering and erosion can break down into sediment. This sediment can then be transported and deposited, eventually forming sedimentary rocks through the process of compaction and cementation.

Is titration a chemical change?
No, titration is a physical process used to determine the concentration of a substance in a solution. It involves adding a reagent to the solution until a specific chemical endpoint is reached. The substances involved in titration do not undergo a chemical change during the process.
What will happen to iron nail kept in cuso4 solution for 2 to 4 hrs?
The iron nail will undergo a redox reaction with the copper sulfate solution, causing the iron to react and form iron oxide, while the copper ions in the solution will be reduced and plate onto the surface of the iron nail, forming a red-brown copper coating on the nail. This process is known as displacement reaction.
Why should ascorbic acid solution not to be exposed to the air?
Ascorbic acid is sensitive to air and can undergo oxidation when exposed, leading to a loss of its antioxidant properties and potential breakdown of the compound. This oxidation reaction can reduce the effectiveness of the ascorbic acid solution.
What solution causes crenation of the red blood cell?
In a hypotonic solution, red blood cells swell and undergo hemolysis, while in a hypertonic solution, they lose water and undergo crenation.
Why do not compounds undergo electrolysis?
Compounds do not undergo electrolysis because electrolysis is the process of using an electric current to decompose a compound into its constituent elements. Compounds are already in a stable form, so they do not break down into their component elements without an external source of energy, such as an electric current.
When atoms join to form a compound they undergo?
A chemical reaction.
