Ответ:
SO4 = negative 2, so you need 2 K+ ions to counteract it, hence K₂
Ответ:
Element-Potassium(K)Sulfate(SO4)
Valency - +1 -2
Now, write the valencies of a elements in the subscript of other..Means write the valency of sulfate in subscript of Pottasium and valency of Potassium in subscript of Sulfate. Like this - K₂SO4..Similarly Magnesium sulfate is MgSO4
