Inhibitor constant (K_i/μm) for various metal fluorides at different pH values

	Ki/μm			nH (shared)a
	pH 6.5	pH 7.5	pH 8.5
MgCl2	39.7 ± 0.7	133 ± 3	708 ± 67	−1.63 ± 0.07
BeSO4	2.6 ± 0.2	2.5 ± 0.3	5.2 ± 0.2	−1.41 ± 0.09
AlCl3	8.5 ± 0.3	12.5 ± 0.2	26.4 ± 0.2	−2.05 ± 0.15
AlCl3·ADP	39.5 ± 0.2	32.4 ± 0.3	42.6 ± 0.7	−1.33 ± 0.11

^a The value of the Hill coefficient in the fitting is shared between experiments performed at the three pH values. In all cases, the n_H value was found to be significantly different from −1.0.
