It is a matter of lattice energy vs. heat of solution. The lattice energy is the energy change associated with the ions in the gas phase forming a solid (crystalline) lattice. It is typically an exothermic process, liberating energy. The heat of solution is the energy change associated with the ions being dissolved by solvent, and can be exothermic or endothermic. If the heat of solution is more exothermic than the lattice energy, than it is energetically favorable for the ionic compound to be solvated. If the lattice energy is more exothermic, than solvation will not occur.

How do ionic compounds form crystals?
When positive ions and negative ions are nearby they are attracted and pair up building an Ionic Crystal.
How do you define the term acid?
Acid, when referring to the science term are proton donors that yield hydronium ions in a water solution, or electron-pair acceptors that combine with electron-pair donors or bases.
Is H2NNH2 an arrhenius base?
Yes, ammonia is an electron pair donor and a Lewis base.
What is the process of reaction of acid and base?
An acid in a water solution, such as HCl (hydrochloric acid), breaks into its ions, Cl- and H+. The hydrogen ion attaches to an unshared electron pair of a water molecule to form a H3O+, or "hydronium" ion. Bases, such as NaOH (sodium hydroxide), also dissociate into ions in water. The hydroxide ion (OH-) from the base lures the extra hydrogen from the hydronium to form another water molecule, and we're left with a salt solution. The entire process is: HCl + H2O + NaOH ---> H3O+ + Na+ + Cl- + OH- ---> NaCl + 2H2O And the overall reaction is: HCl + NaOH ---> NaCl + H2O
A conjugate acid-base pair differs by several h ions?
true

What ions does a neutral solution contain and what is the quantity of each?
A neutral solution can contain ions of hydrogen, hydroxide, and the cation and anion of any neutral salt. There are equal numbers of hydrogen and hydroxide ions, and also an equal (but usually different) number of the other pair of ions.

An acid base pair is known as what?
When a acid/base pair with a common anion (salt ion) is meant, then it is called a conjugated pair. When both of them are in the same solution in about equal amounts then they form a buffer solution, so they also can be named as buffering pair.
Is H2NNH2 an arrhenius base?
Yes, ammonia is an electron pair donor and a Lewis base.
What is the plural form of the word pair?
Pair or pairs is the plural form of pair. Both are acceptable.
Why protein solution turns purple when copper sulfate solution is added?
Copper sulfate solution provides cupric ions that react with the peptide bonds present in the protein molecule. The test is called as biuret test, as it was originally given by biuret compound.( when urea is heated it forms biuret). The reaction is due to the formation of complex between the cupric ions and lone pair of electrons present on the Nitrogen and Oxygen atoms of peptide bond.

How can you determine if a ordered pair is a solution?
Substitute the values of the ordered pair into the relation. If the equation is valid then the ordered pair is a solution, and if not then it is not.
When is it possible for an ordered pair to be the solution of more than one equation?
Always. Every ordered pair is the solution to infinitely many equations.
