0.154M `CrO_4^(2-)` can convert 40ml, 0.25M `S_2O_3^(2-)` to `SO_4^(2-)` and itself reduces to `Cr(OH)_4^-` then find volume of `CrO_4^(2-)` used in this process (in ml).

In basic medium CrO_4^(2-) oxidises S_2O_3^(2-) to form SO_4^(2-) and itself changes into Cr(OH)_4^(-) . The volume of 0.154 M CrO_4^(2-) required to react with 40 mL of 0.25 M S_2O_3^(2-) is "___" mL.

In basic medium, CrO_(4)^(2-) oxidises S_(2)O_(3)^(2-) to form SO_(4)^(2-) and itself changes to Cr(OH)_(4)^(-) . How many mL of 0.154M CrO_(4)^(2-) are required to react with 40mL of 0.308 M S_(2)O_(3)^(2-) ?

Acidic K_(2)Cr _(2)O_(7) oxidises S_(2) to K_(2)SO_(4) and itself reduced into

Consider the following conversion CrO_4^(-2) ⇋ Cr^(+3) find n factor of CrO_4^(-2) is

K_(2)Cr_(2)O_(7)+NaoH to CrO_(4)^(2-)

K_(2)CrO_(4) is converted to K_(2)Cr_(2)O_(7) by
