In the quantitative volumetric analysis, why is K_(2)Cr_(2)O_(7) preferred over Na_(2)Cr_(2)O_(7) ? |
| Answer» Solution :`Na_(2)Cr_(2)O_(7)` is a deliquescent and so it is not used to prepare PRIMARY standard solution, WHEREAS `K_(2)Cr_(2)O_(7)` is not a deliquescent substance and hence it is preferred over `Na_(2)Cr_(2)O_(7)`. | |
