    present. To access the degree of the alkyl halide formed (1° or 2° halide) and to determine whether Markovnikov’s addition occurred‚ two qualitative tests can be used: (a) reaction with alcoholic silver nitrate solution and (b) reaction with sodium iodide in acetone. For the silver nitrate test‚ one drop of alkyl halide is added to 2 mL of 0.1 M solution of silver nitrate in

    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

    which of the two will reacted with potassium iodide inside the breaker‚ as the latter passed from the beaker into the tube‚ the glucose/starch solution’s change of color showed that the potassium iodide was small enough that it able to pass through from the solution and into the bag. After the Benedict test‚ glucose from the bag was also founded small enough that it can exit from the bag and into and solution. In the end‚ glucose and potassium iodide was the only two that is capable to move freely
