In the lab we synthesised nickel (II) ammine tetraflouroborate using hydrated nickel chloride and ammonia then this solution was added to a slotion of ammonia and ammonium tetraflouroborate,now im struggling to write a fully balanced chemical reaction.Would anyone please help with the equation?

1 answer

NiCl2.6H2O + 6NH3 ==> Ni(NH3)6Cl2 + 6H2O

Ni(NH3)6Cl2 + 2NH4BF4 ==> [Ni(NH3)6][BF4]2 + 2NH4Cl

Add the two equations to obtain an overall equation if that's what you want.
By the way I think your spelling of tetrafluoroborate is incorrect.
