This page describes and explains the redox reactions involving halide ions and concentrated sulphuric acid. It uses these reactions to discuss the trend in reducing ability of the ions as you go from fluoride to chloride to bromide to iodide. There are two different types of reaction which might go on when concentrated sulphuric acid is added to a solid ionic halide like sodium fluoride, chloride, bromide or iodide. The concentrated sulphuric acid can act both as an acid and as an oxidising agent. The concentrated sulphuric acid gives a hydrogen ion to the halide ion to produce a hydrogen halide. Because this is a gas, it immediately escapes from the system.

The structural properties of these electrolyte films were examined by X-ray diffraction XRD studies. The proton conductivity and impedance of the electrolyte were studied with changing sulfuric acid concentration from 0 to 5. The highest conductivity of PVA 0. The fabricated cells give open circuit voltage of 3. This is a preview of subscription content, log in via an institution to check access. Rent this article via DeepDyve. Institutional subscriptions.

Direct link to this balanced equation:. A chemical equation represents a chemical reaction. It shows the reactants substances that start a reaction and products substances formed by the reaction. However, this equation isn't balanced because the number of atoms for each element is not the same on both sides of the equation. A balanced equation obeys the Law of Conservation of Mass, which states that matter is neither created nor destroyed in a chemical reaction. This is the most straightforward method. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. Process: Start with the most complex molecule or the one with the most elements, and adjust the coefficients of the reactants and products until the equation is balanced.

H 2 SO 4 is categorized as a strong acid. Sodium iodide is formed by the reaction of sodium metal and iodine. These two components react to generate fumes of hydrogen iodide and the color of the resultant solution is red. Let us discuss the product formed when H 2 SO 4 reacts with NaI, the type of reaction, the net ionic equation and many other related topics in this article. Sulphuric acid reacts with sodium iodide to give sodium sulphate, hydrogen sulphide, iodine and water. We need a burette, conical flask, burette holder, volumetric flask, and beakers for this titration. The phenolphthalein or methyl orange indicator can be used because it is a strong acid versus weak base reaction, and its endpoint is pink to colorless. The burette was filled with standardized H 2 SO 4 and NaI was taken in a conical flask along with the respective indicator. H 2 SO 4 is added dropwise to the conical flask and the flask was shaking constantly. After a certain time when the endpoint arrived, indicator changes its color and the reaction was done.

Interviews Answers to Science Questions. It uses these reactions to discuss the trend in reducing ability of the ions as you go from fluoride to chloride to bromide to iodide. Heat will be given out when the changes involving the sulphuric acid occur. The amount of heat given out by the half-reaction involving the sulphuric acid must be great enough to make the reactions with the bromide or iodide feasible, but not enough to compensate for the more positive values produced by the fluoride and chloride half-reactions. This isn't the total enthalpy change for the whole reaction. It involves looking at the equation and adjusting the coefficients to get the same number of each type of atom on both sides of the equation. The simplified explanation that we mentioned earlier concentrates on the less important fall in the amount of energy needed to remove the electron from the ion. Download citation. Exploring the changes in the various energy terms Which individual energy terms in the table are most important in making the halogen half-reaction less endothermic as you go down the Group? The concentrated sulphuric acid can act both as an acid and as an oxidising agent. That's misleading! If I were you, I wouldn't bother to follow this up unless there is some overwhelming reason to! Atomisation energy is the energy needed to produce 1 mole of isolated gaseous atoms starting from an element in its standard state gas for chlorine, and liquid for bromine, for example - both of them as X 2. The values for the lattice enthalpies for other solid halides would be different, but the pattern will still be the same.

There are two different types of reaction which might go on when concentrated sulphuric acid is added to a solid ionic halide like sodium fluoride, chloride, bromide or iodide. DrDick Sr. This falls because the ions are getting bigger. Process: identify the oxidation numbers, determine the changes in oxidation state, balance the atoms that change their oxidation state, and then balance the remaining atoms and charges. We have concentrated on the energetics of the process starting from solid halide ions because that's what you use if you try to oxidise them using concentrated sulphuric acid. Accepted : 03 October The table shows the energy changes which vary from halogen to halogen. The reduction of the sulphuric acid is more complicated than before. The simplified explanation that we mentioned earlier concentrates on the less important fall in the amount of energy needed to remove the electron from the ion. Similar topics 5.
