Dissolving ionic compounds in water When an ionic compound dissolves in water two processes occur 1. Energy has to be taken in to break up the lattice and separate the positive and negative ions. This is the lattice enthalpy 2. The ions become surrounded by solvent and bonds form - energy is released when these ions form bonds with water molecules.

Lithium may also be absorbed via the lungs. A systemic resorption of lithium was shown in a study on 27 intensive care unit patients, who were mechanically ventilated with lithium-chloride-coated heat and moisture exchangers for at least 5 days. Serum lithium was non-detectable at the first measurement, whereas 0.01-0.05 mM appeared in the blood from the 1st to the 4th day. (ii) Give the name of the compound with the formula NH 4 NO 3 (b) Sodium oxide, Na 2 O, is an ionic compound. The sodium and oxide ions are held together by ionic bonds. (i) State the meaning of the term ionic bond. (ii) The diagram shows the arrangement of the electrons in a sodium atom and in an oxygen atom. Calculate the amount of heat required (in kilojoules) to heat 5.00 grams of water from -16.0 C to 11.0 c.-enthalpy of vaporization for water is 40.56 kJ/mol-enthalpy for fusion of water is 6.007 kJ/mol -specific heat for ice is 2.090 J/(gram x *C)-specific heat for water is 4.184 J/(gram x *C)-specific heat for steam is 2.030 J/(gram x *C) The enthalpy change for an ionic compound MX consisting of ions with single charges is represented as M+ (g) + X− (g) → MX (s) Na+ (g) + Cl- (g) Enthalpy Enthalpy of lattice dissociation Enthalpy...

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.

Complete the energy level diagram to show the position of the lithium iodide solution. Label the diagram to show ûH, the molar enthalpy change. (2) (Total for Question 5 = 11 marks)

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.
