Document Summary

It can absorb, store, and release large amounts of energy in the form of heat, making it a great insulator against temperature changes. It is a universal solvent because it can solvate most polar molecules/ ions: hydrogen boding is present between water molecules. If the solvation enthalpy > lattice enthalpy, a solid will dissolve in water. Solute properties and electrolytes: solutions with dissolved ions can conduct electricity. Ions act as carriers of electrical charge in a solution: electrolytes- solutes that produce ions in solutions that can conduct electricity, strong electrolytes dissolve completely into ions in water, e. g. Silver chloride rule 4 states that chlorides are soluble, but rule 3 states that silver salts are insoluble. Thus, we follow the lower numbered rule, which is that silver chloride is insoluble. Net ionic reactions: look at whether a compound is soluble or not.
