Metal and Non-metal Inorganic compounds composed of just two elements‚ metal cations (positive ions) and non-metal anions (negative ions). These are referred to as metal-nonmetal binary compounds. There are two types of metals‚ some metals form cations with only one charge (e.g.Na+‚ K+) while other cations form

in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write net ionic equations for precipitation reactions. A detailed view of the results can be found in the table below. Cations used: Barium‚ Copper‚ Iron‚ Sodium‚ Cobalt‚ Nickel Anions used: Nitrate‚ Carbonate‚ Chloride‚ Hydroxide‚ Sulfate‚ Bicarbonate‚ Iodide‚ Phosphate

rule‚ reactivity increases as you move down a group in the periodic table. This means in regards to solubility that the more you farther you move down the group the more insoluble the element is when combined with hydroxides‚ chlorides‚ bromides‚ iodides‚ sulfates‚ carbonates‚ and oxalates. My results were consistent with this theory in that the mixtures went from no reaction to forming a precipitate or from forming a light precipitate to a heavy one as the elements moved down the periodic

Chemical equilibrium is said to be dynamic because‚ at equilibrium‚ there are reactions continually occurring. The rate of the forward reaction equals the rate of the reverse reaction. Equilibrium Constants At equilibrium as much hydrogen iodide is being decomposed as is formed and so the concentrations of all three substances remains constant. Kc is the equilibrium constant in terms of molar concentration. This is known as the Equilibrium Law. The equilibrium constant shows the position
