Value of z in the formula YBa 2 Cu 3 O 7 − z has to be determined. Concept Introduction: A superconductor is a material wherein electrical conductivity becomes infinite and from which magnetic flux field is expelled. Superconductor has a critical temperature below which resistance drops abruptly to zero. Iodometric titration is a type of titration reaction in which iodides reacts with another oxidizing agent in acidic or neutral medium. As a result of this, iodides are converted to iodine and this formed iodine is back titrated against another standard reducing agent (usually sodium thiosulphate) of known concentration.
