A solution of `Na_2S_2O_3` is standardized iodometrically against `0.167g` of `KBrO_3`. This process requires `50mL` of the `Na_2 S_2O_3` solution. What is the normality of the `Na_2S_2O_3.` ?

A solution of Na_(2)S_(2)O_(3) is standardized iodometrically against 0.167g of KBrO_(3) . The process requires 50mL of the Na_(2)S_(2)O_(4) solution. What is the normality of the Na_(2)S_(3)O_(3)?

A solution of Na_2S_2O_3 is standardised iodometrically by using K_2Cr_2O_7 . The equivalent weight of K_2Cr_2O_7 in this method is:

Na_(2)S_(2)O_(3) is prepared by :

Na_2S_2O_3. 5H_2O is used in photography to

The density of 3 M solution of Na_2S_2O_3 is 1.25g/mL . What is % by weight of Na_2S_2O_3 ?

What is the percentage composition of Na_(2)S_(2)O_(3).5H_(2)O ?

Na_(2)S_(2)O_(3) is oxidized by I_(2) to give

Aqueous solution of Na_(2)S_(2)O_(3) on reaction with CI_(2) , gives

1.5 g of a mixture containing As_2O_5 , Na_2HAsO_3 , and some inert impurities is dissolved in water, and the solution is kept neutral by adding excess of NaHCO_3 . The solution when titrated with 0.1 M I_2 required 35.0 nL of it for complete titration. The solution is then acidified and excess of KI is added to it. The I_2 liberated required 35.0mL of 0.3 M Na_2S_2O_3 solution for complete titration. Find the percentage composition of the mixture (Atomic mass of As is 75, Na is 23 and O is 16.)

In the estimation Na_(2)S_(2)O_(3) of using Br_(2) the equivalent weight of Na_(2)S_(2)O_(3) is :
