The balanced chemical equation for this reaction is:
CuSO4 + 2KF → CuF + K2SO4
In this reaction, the copper(II) ion (Cu2+) in CuSO4 is reduced to copper(I) ion (Cu+), while the sulfate ion (SO42-) from CuSO4 combines with two potassium ions (K+) from KF to form potassium sulfate (K2SO4). The fluoride ions (F-) from KF react with the copper(I) ions to form copper(I) fluoride (CuF).
