    People believe that trouble is far away but it is here to stay and cannot be redirected any way that you may wish Net ionic equations are equations that show only the soluble‚ strong electrolytes reacting (these are represented as ions) and omit the spectator ions‚ which go through the reaction unchanged. When you encounter net ionic equations on the SAT II Chemistry test‚ you’ll need to remember the following solubility rules‚ so memorize them! Also keep in mind that net ionic equations‚ which

    This experiment was a Landolt Iodine clock reaction - Oxidation of Bisulphite by Iodate. It involved conducting three measured experiments. The first variable tested was concencentration. This was tested by conducting two experiments‚ each varying the concentration of either the NaHSO3 or KIO3. The varying of NaHSO3 involved using 0.1 Molar of KIO3 against decreasing concentrations of NaHSO3 (0.25 M‚ 0.125 M‚ 0.0625 M and 0.03125 M). When decreasing the concentration of KIO3‚ 0.25 M of NaHSO3 was

The general electronic configuration of transition metal is (n–1) d1–10ns1–2. Exceptions in electronic configuration are due to (a) very little engery difference between (n–1) d and ns orbitals and (b) extra stability

    The stopper is removed carefully from the conical flask and 2 mL of the manganese sulfate solution is added‚ discharging the reagent from the tip of a pipette put well below the water surface. Stopper is replaced. 3. Similarly‚ 2 mL of the alkaline-iodide solution is introduced. 4. The stopper is placed in the bottle‚ be sure that no air becomes entrapped. Some overflow may occur. The content is mixed thoroughly by inversion and rotation. Manganese hydroxide is precipitated and will settled on standing

    CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant
