When an ionic substance dissolves in water, its enthalpy of solution depends on the difference between its lattice enthalpy and the enthalpies of hydration of its ions. The enthalpy of solution can be calculated with the help of an enthalpy cycle diagram. Calculating the enthalpy of solution,
Complete the enthalpy diagram for an ionic compound dissolving in water.
Some ionic compounds give off heat when dissolving in water and others absorb heat. Whether the dissolution process of a given ionic compound gives off or absorbs heat depends on the strength of the intermolecular forces holding the solid together, as well as those between the ions and the water once dissolved. Enthalpy change of solution and Enthalpy change of Hydration When ionic compounds dissolve in water, there is usually a temperature change. Sometimes this is exothermic (e.g. dissolving calcium chloride) and sometimes endothermic (e.g. dissolving ammonium nitrate). The experiments are easy to carry out in a laboratory, and the usual equations ... Chemistry questions and answers.

Ionic compounds are often soluble in water, because the attractions formed between ions and water are frequently strong enough to make their solution either exothermic or only slightly endothermic. For example, the solution of sodium hydroxide is exothermic, and the solution of sodium chloride is somewhat endothermic. Dissociation. An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. Many ionic compounds are soluble in water, however, not all ionic compounds are soluble. Ionic compounds that are soluble in water exist in their ionic state within the solution. You will notice in Figure 7.2 that the sodium chloride breaks apart into the sodium ion and the chloride ion as it dissolves and interacts with the water molecules. a. Water, H 2O ionic compound covalent compound b. Sodium chloride, NaCl ionic compound covalent compound c. Calcium carbonate, CaCO 3 ionic compound covalent compound d.

Dissolving an ionic salt in water Computer Simulation and Computer Animation A short computer animation illustration how positive and negative ions in a solid ionic compound dissolve in water might be used to accompany dissolving salts in water demonstration. The solution (including the reactants and the products) and the calorimeter itself do not undergo a physical or chemical change, so we need to use the expression for specific heat capacity to relate their change in temperature to the amount of heat (q cal) that they have exchanged (Eqn. 3). In Eqn. 3, m is the mass (mass of the reactants + mass of water + mass of calorimeter), C is the ... the enthalpy ch an ge when one mole of an ionic compound dissolves in sufficient water to produce a solution of in f in ite dilution.

Ionic compounds dissolve in water because the water molecules hydrate the ions. > To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. Water is a polar molecule. It has a permanent dipole. The "O" atom has a partial negative charge, and the "H" atoms have a partial positive charge.

The enthalpy change of solution is the enthalpy change when 1 mole of an ionic substance dissolves in water to give a solution of infinite dilution. Enthalpies of solution may be either positive or negative - in other words, some ionic substances dissolved endothermically (for example, NaCl); others dissolve exothermically (for example NaOH).
Hydrolysis
When water dissolves a substance, the water molecules attract and "bond" to the particles (molecules or ions) of the substance causing the particles to separate from each other. The "bond" that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water's polarity.

A common example of this type of ionic compound is sodium chloride, commonly known as table salt. As noted at the beginning of this module, spontaneous solution formation is favored, but not guaranteed, by exothermic dissolution processes. While many soluble compounds do, indeed, dissolve with the release of heat, some dissolve endothermically.

We can generally assume that salts dissociate into their ions when they dissolve in water. Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.
