A positive value for the reduction potential means that it has a higher propensity for reduction, whereas a lower value for the reduction potential means that it is less likely to be reduced (i.e. it will resist reduction). Since $\ce{Na+}$ has a lower reduction potential than $\ce{H+}$, we can expect that $\ce{H+}$ will be preferentially reduced.$\begingroup$ @YUSUFHASAN, if you’re talking about Cr(II) being a good reducing agent, then fair enough; this is partly explained by CFSE/LFSE, and that is why in the graphs above there is a dip in E° although there is …$\begingroup$ @YUSUFHASAN, if you’re talking about Cr(II) being a good reducing agent, then fair enough; this is partly explained by CFSE/LFSE, and that is why in the graphs above there is a dip in E° although there is …

Currently, the traditional treatment for tooth decay is fluoride, which does not control biofilm (the cause of tooth decay) or prevent enamel demineralization. In search of a more effective treatment, the research team employed a combination of ferumoxytol (Fer) and stannous fluoride (SnF2) to fight tooth decay.A species with a higher reduction potential possesses a higher tendency to acquire electrons and be reduced. Conversely, a species with a higher oxidation potential possesses a higher tendency to lose electrons and be oxidized (Zanello 2003 ).
