Question

A white sed­i­ment forms, which is sol­u­ble in al­ka­lis:

NaCl + K[Sb(OH)₆] ↔ Na[Sb(OH)₆]↓ + KCl

what would be the reaction?

Answer 1

displacement reaction
in the above reaction na is displaced by k and k is displaced by [ Sb (oh)6]
hope it help's u

Answer 2

Hi mate... Some values from my side

First of all in an acid medi­um, the reagent breaks down with the for­ma­tion of a white amor­phous sed­i­ment of meta-an­ti­mon­ic acid HS­bO₃ only.

So,

K[Sb(OH)6] +HCl ↔ KCl + H₃S­bO₄ + 2H₂O

H₃S­bO₄ ↔ HS­bO₃↓ + H₂O
