The electrical conductivity of polycrystalline pellets of ZnSO 4  · 7 H 2 O, MgSO 4  · 7 H 2 O, CuSO 4  · 5 H 2 O, KAl(SO 4 ) 2  · 12 H 2 O, NH 4 Al(SO 4 ) 2  · 12 H 2 O and KCr(SO 4 ) 2  · 12 H 2 O was measured. By coulometry the role of protons as charge carriers was determined. A correlation is given between the strength of hydrogen bonds and the activation energies for the proton conductivity.
