← In a titration, 15.0 mL of 0.0140 mol/L potassium bromate oxidises the iron(II) in a 30.0 mL sample, in acid. The reaction is BrO₃⁻ + 6Fe²⁺ + 6H⁺ → Br⁻ + 6Fe³⁺ + 3H₂O. What is the concentration of iron(II)?Electrons flow through the wire of a working Daniell cell. In which direction do they go, and how does the current of the cell move? →
