Why is CaF2 soluble in water?

Calcium fluoride (CaF2) is sparingly soluble in water due to its strong ionic bond between the calcium and fluoride ions. When CaF2 is placed in water, the ions dissociate and interact with the polar water molecules, which helps break the ionic bond and allows CaF2 to dissolve in water. However, CaF2 has low solubility in water because the attraction between the ions in the solid state is strong compared to the interactions with water molecules.


What is the correct diagram for caf2?

The correct diagram for CaF2, calcium fluoride, consists of Ca2+ ions surrounded by eight F- ions in a cubic closest-packed (face-centered cubic) arrangement. Each fluoride ion is in contact with four calcium ions.


Why do ionic compounds behave somewhat like polar molecules in a solution?

Because they dissociate into charged ions. Because they dissociate into charged ions.


When acid dissociate they release what?

When acids dissociate, they release hydrogen ions (H+). This process increases the concentration of H+ ions in the solution, making it acidic.


Is CaF2 an example of an ionic crystal?

Yes, CaF2 is an example of an ionic crystal as it is composed of calcium ions (Ca2+) and fluoride ions (F-) held together by ionic bonds. Ionic crystals typically have a repeating pattern of positively and negatively charged ions in a lattice structure.


When bases dissociate they release?

hydroxide ions


Explain what the formula CaF2 tells you about this compound?

Ca+2 F-1 <----- these are the ions and their charges Ca+2 F-1 F-1 <----- the charges have to add up to zero, so two -1 fluorine ions cancel out one +2 calcium ions CaF2 <---- simplify


Does Water molecules dissociate to form h o2 ions?

Water's high heat of vaporization allows it to cool us off when we sweat


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

oxygen


What type of force holds ions together in salts such as CaF2?

Ionic bonds hold ions together in salts such as CaF2. These bonds form when one atom gives up electrons to another, resulting in positively and negatively charged ions that are attracted to each other.


Does acetic acid dissociate in water and what are the products of this dissociation?

Yes, acetic acid does dissociate in water. The products of this dissociation are hydrogen ions (H) and acetate ions (CH3COO-).


How many moles of Ca are there in 0.18moles of Ca F2?

There are 0.18 moles of Ca2+ ions in 0.18 moles of CaF2.
