Why is [math]\mathrm{Cr}^{6+}[/math] (hexavalent chromium) more toxic than [math]\mathrm{Cr}^{3+}[/math] (trivalent chromium)?
I was wondering if you could help me understand why [math]\mathrm{Cr}^{6+}[/math] is more toxic than [math]\mathrm{Cr}^{3+}[/math]?
Sure! One reason is that [math]\mathrm{Cr}^{6+}[/math] is more soluble in water than [math]\mathrm{Cr}^{3+}[/math]. This means it can more easily enter cells and interact with biological molecules, causing damage.
