Factors Affecting the Equilibrium Reaction of Iron (III) and Thiocyanate ions

Factors influencing the equilibrium reaction of iron (III) and thiocyanate ion The temperature change of iron (III) iron thiocyanate (including iron (III) ion Fe 3+ (aq) and thiocyanate ion SCN - (- aq) How will it affect the absorbance of the solution? - Temperature of 25 ° C, 30 ° C, 35 ° C, 40 ° C, 45 ° C, 50 ° C, 55 ° C and 60 ° C (using iron (III) iron thiocyanate at various temperatures Aq) Digital Balance the water bath and check the temperature using a digital thermometer connected to the data logger. - The rate of formation of thiocyanate ion as measured by extent of color change using a colorimeter at 600 seconds after mixing of reactants.

Nomenclature of the reaction of tin (ii) and tin (iv) compounds The reaction of iron (ii) and iron (iii) compounds was tested. Then convert copper (ii) to copper (i). Method: Please refer to the method table. Materials: Test tube (4) Iron (iii) ferric chloride ferricyanide test tube rack iron (ii) copper sulfate (ii) tin sulfate (ii) sodium chloride ammonium hydroxide ammonium hydroxide thiocyanate (iv) chloride hydrogen dixide distilled water Ammonium thiocyanate ammonium chloride (ii) Ammonium ammonium thiocyanate After observation: Small white crystals produce rotten smelling eggs distilled water and a transparent transparent liquid odor. A clear liquid precipitate of brown liquid and brown ammonium sulfide green was also formed. Small white crystals of tin (iv) chloride produce a yellow liquid rather than distilled water, which is as transparent as above and has a yellow precipitate. Odorless

Even at low temperatures, iron wool reacts rapidly with fluorine to form a white complex iron (III) complex. When chlorine comes in contact with heated iron, they react to form iron (III) chloride. However, if the reaction conditions are moist, the reaction will produce a reddish brown product. Iron can also react with bromine to form iron (III) bromide. The compound was reddish brown under dry conditions. The reaction between iron and bromine is lower than the reactivity with fluorine or chlorine. Hot iron reacts with iodine, but forms iron iodide (II). This compound may be gray, but the reaction is not reliable as it is always contaminated with excess iodine. Iron is less likely to react with iodine than it reacts with lighter halogens
