Reference no: EM131075933

The extent of corrosion in the steel reinforcing rods (rebar) of concrete is measured by the galvanic cell shown in the diagram of the instrument. The half-cell of the probe is usually a AgCl/Ag redox couple: AgCl + e-= Ag Cl- (1.0 M) E standard= 0.23 V Corrosion is said to be severe if the cell potential is measured at greater than 0.41 V. Under these conditions, What is the iron(II) concentration on the rebar? Fe 2+ + 2e-= Fe E standard= -0.44 V Explain using nerst equation.
