1.	The salt KHC_(2)O_(4)H_(2)C_(2)O_(4).4H_(2)Omay be used as reducing agent as well as an acid. Choose thecorrect option (S):
Answer» The equivalent weight of the salt is 72.5 g-`"equivalent"^(-1)`, when reacted with acidified `KMnO_4`SOLUTION. The equivalent weight of the salt is 145 g-`"equivalent"^(-1)` , when reacted with NaOH solution, The volume of `CO_2`liberated at STP by 1 g of salt when reacted with excess of acidified `KMnO_4`is 309 ml. The number of ionizable HYDROGEN ion is one. Solution :With `KMnO_4`the given salt act as reducing agent . So for each oxalate ion it.s n-factor is 2. So total salt n-factor is 4 and Oxalate ion releases `CO_2`When it reacts with NaOH, it SHOWS acidic nature. The salt has basicity 3.
