Find out the strength of H2O2 in g/lit-1 ?, Answer with step by step detailed solutions to question from Arihant’s BITSAT Prep Guide, Hydrogen- Excess of Kl and dil. H2SO4 were mixed 50 mL H2O2. Thus,.
12/2/2015 · KIO3 + 5KI + 3H2SO4 = 3K2SO4 + 3H2O + 3I2 As per this equation, 1 mole of the iodate needs 5 moles of the iodide to form 3 moles of free iodine. So, if KIO3 and KI are taken in the exact stoichiometrical molar ratio of 1:5, the product should be only iodine, I2, together with K2SO4 and H2O.

6/15/2009 · (Q-3)-50ml of aqueous solution of H2O2 was heated with excess KI solution in dil . H2SO4 .The liberated iodine required 200ml of 0.1N . Na2S2O3 solution for complete reaction.Calculate the concentration of H2O2 in gm/litre.What is its volume strength? (answer is 2.24) P.S: thx for.
2 moles of BaCl2 reacts with excess of dil H2SO4 .The number of moles of BaSO4 formed is – 4521204, 7/20/2016 · It is basically used to convert an Alkyne into a Ketone. The reaction is called Kucherov Reaction. The reaction can be understood by following mechanism.
Dil . HCl test:To a portion of the salt solution, add dil HCl. Pass the gas evolved through lime water. Brisk effervescence and evolution of colourless odourless gases. Lime water turns milky. The gas evolved is CO 2. CO 2 reacts with lime water to form white precipitate of CaCO 3.
H2SO4 increase the acidic content of the solution so as to prevent MnO4 (purple) to reduced to MnO2(dark brow). Hence sulfuric acid is stable in the present of strong oxidising agent. If HCl acid is use it will be oxidised to Cl and make the end point much higher.
