hypo reduces iodine to iodide, itself oxidises to sodium tetrathionate. n-factor of hypo is?

A mixture of ethyl iodide and n - propyl iodide is treated with sodium metal in presence of ethoxyethane . The hydrocarbon which is not formed is

Iodate ions (IO_(3)^(-)) can be reduced to iodine by iodide ions. The half equations which represent the redox reaction are: IO_(3)^(-)(aq.)+6H^(+)(aq.)+5e^(-) to (1)/(2)I_(2)(s)+3H_(2)O(l) . . . (i) I^(-)(aq.) to (1)/(2)I_(2)(s)+e^(-) . . . (ii) How many moles of iodine are produced for every mole of iodate ions consumed in the reaction?

When ethyl iodide and n-propyl iodide are allowed to react with sodium in the presence of dry ether, the number of alkanes that would be produced is

The compound listed below that would be produced in greatest yield is : Methyl iodide and n-propyl iodide reacts with sodium metal to produce organic compounds

Iodate ions can be reduced to iodine by iodide ions as per the given redox reaction in acidic medium. lO_(3)^(-)(aq)+l^(-)(aq)tol_(2)(S) . How many moles of iodine are produced for every mole of iodate ions consumed in the reaction?

Iodine titration can be iodemotric or iodimetric depending on using iodine directly or indirectly is an oxidising agent in the redox titration. a. Iodimetric titration in which a standard iodine solution is used as an oxidant and iodine is directly or indirectly titrated against a reducing agent. For example. 2CuSO_(4)+4KJtoCu_(2)I_(2)+2K_(2)SO_(4)+I_(2) b. Iodimetric procedures are used for the datermination of strength of reducing agent such as thiosulphates, sulphites, arsenties adn stanous chloride etc. by titrating them against standard solution of iodine in a burette. 2Na_(2)SO_(3)to2 NaI +Na_(2)S_(4)O_(6) Starch is used as indicator near the end point whilch form blue colour complex with I_(3)^(-) . The blue colour disappeams when there is not more of free I_(2) . The volume of KI solutioin used for CuSO_(4) will be

When 319.0 gm of CuSO_(4) in a solution is related with excess of 0.5 M KI solution, then librated iodine required 200 ml of 1.0M Na_(2)S_(2)O_(3) for complete relation. The percentage purity of CuSO_(4) in the sample is

Assertion: Aryl iodides can be prepared by reaction of arenes with iodine in the presence of an oxidising agent. Reason: Oxidising agent oxidises I_(2) into HI.

I^(-) reduces IO_(3)^(-) to I_(2) and itself oxidised to I_(2) in acidic medium. Thus, final reaction is

12. g of an impure sample of arsenious oxide was dissolved in water containing 7.5 g of sodium bicarbonate and the resulting solution was diluted to 250 mL . 25 mL of this solution was completely oxidised by 22.4 mL of a solution of iodine. 25 mL of this iodine solution reacted with same volume of a solution containing 24.8 g of sodium thiosulphate (Na_(2)S_(2)O_(3).5H_(2)O) in one litre. Calculate teh percentage of arsenious oxide in the sample ( Atomic mass of As=74 )
