    Writing Half Reaction and Net Ionic Equation Going back to our first concept or topic‚ we’ve learn how to identify the Oxidizing and Reducing agent and the Oxidation as well as the Reduction. In this part of the Redox reaction or in this step‚ it is very important that you already know the Oxidizing and Reducing agent for us to find the half reaction. In this step or part‚ we will also learn how to balance using the addition of electrons in both sides if necessary. After this step we can now write

    colorless‚ the end point in the titrations using potassium permanganate as the titrant can be taken as the first permanent pink color that appears in the solution. This titration involves the oxidation of Fe2+ ions to Fe3+ ions by the permanganate ion‚ and is carried out in sulfuric acid solution to prevent the air oxidation of the ferrous ion. The end point of the titration is sharpened markedly if phosphoric acid is present. The reason being the Fe3+ ion by itself has a yellow color that can partly mask

    DOWNLOADED FROM WWW.STUDIESTODAY.COM DOWNLOADED FROM WWW.STUDIESTODAY.COM d – AND f – BLOCK ELEMENTS Electronic Configuration of Transition Metal/Ions The d-block element is called transition metal if it has partly filled d-orbitals in the ground state as well as in its oxidised state. 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

    force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple to determine because they are given oxidation states similar to their charges. However

    Laboratory exercise 3 : Quantitative analysis of vitamin C contained in a fruit juice Aim: To investigate the amount of vitamin C found in all kinds of fruit juice Introduction : Vitamin C is an antioxidant‚ along with vitamin E‚ beta-carotene‚ and many other plant-based nutrients. Antioxidants block some of the damage caused by free radicals‚ substances that damage DNA. The build-up of free radicals over time may contribute to the aging process and the development of health conditions such as

    of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally because of the balanced equation the ratio of the mass and the mole has to be the same; by this we can check the actual equation and the actual oxidation number of
