chlorine-containing metabolites‚ such as chlorite and chloride ions. Abdel-Rahman et al. (1980b) developed a method to quantitatively and qualitatively measure the metabolites of chlorine dioxide (e.g.‚ ClO2-‚ and ClO-) in biological fluids. These biomarkers can be used to indirectly measure chlorine dioxide exposure. The concentration of residual chlorite ion in vegetables and eggs treated with sodium chlorite was determined by UV-ion chromatography (Suzuki et al. 1997). Sodium chlorite was extracted

of the concentration of chlorine ions Aim: To compare the concentration of chloride ions in pool and tap water respectively. Background: Tap water contains a variety of dissolved ions such as Ca2+‚ Mg2+‚ Na+‚ HCO3- and Cl-. In this experiment we will determine the concentration of the Cl- ions‚ and comparing it to the concentration found in a sample of pool water. The method used is the standard one for determining the concentration of chloride ions: titration with silver nitrate

called ions. Those ionic substances are broken down by electrolysis. Electrolysis is the breakdown of a substance by electricity‚ and it only happens in liquids. The liquids that can be electrolyzed are called electrolytes. When said electrolyzed‚ means that the compounds in solutions are broken down when they conduct electricity. Its necessary the use of electrodes since it conducts the electricity to the solution. The electrodes are needed to be an anode‚ which receives the negative ions‚ and the

to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n Chemical Kinetics is the chemistry of how fast
