WebAnswer (1 of 2): When sulfur dioxide comes in contact with a filter paper dipped in acidified potassium dichromate solution (K2Cr207 + dil.H2SO4), the paper’s color changes from orange-red to green. K2Cr2O7 + 3SO2 + H2SO4 = K2SO4 + Cr2(SO4)3 + H2O Sulphur dioxide reduces the dichromate to green...

Hydrogen burns in oxygen to form water.2.) Web16 Aug 2012 · (PS it acts as both oxidising and reducing agent) Oxidation no. of Te changes from 0 to +4 in TeO 2. Unlike sulphur Te cannot show +6 oxidation state as it is highly unstable due to inert pair effect. Therefore there can only be a decrease in it oxidation state (it can decrease to -2, +2). falafel backen

Web26 Jul 2016 · Ultrasonic power, irradiation time, reducing agent, solvent, HCl, NaOH, and the surfactant were changed in order to investigate the effect of preparation parameters on the morphology and particle ... WebOn moving down the group, acidic character decreases (in the same oxidation state). So, SO2 and SeO2 are acidic, whereas TeO2 and PoO2 are amphoteric. Reducing property of dioxides decreases from SO2 to Te 02. SO, is reducing agent, as +6 oxidation state of S is more stable than +4 while Teo, is an oxidising agent. Web8 Apr 2024 · Strong reducing agents are weak oxidizing agents. Sodium, hydrogen, and lithium are examples of strong oxidizing agents. While weak reducing agents cannot lose electrons easily. Fluorine, chlorine, iron etc. are weak reducing agents. We can know the strength of reducing agents by electrochemical series as well. hi tec tarantula
