square = rst addition of HCl; lled circle = rst addition of NaOH; empty square = second
addition of HCl; empty circle = second addition of NaOH; and (b) point of zero charge of red
mud; lled squares = the titration with red mud, lled diamonds = the blank titration. The
point of zero charge is given by the intersection of the two pH curves (Pulford etal., 2012).
