1.	Standard electrodepotential values, E^(@) at Al^(3+)//Al is -1.66 V andthat of Tl^(3+)//Tl is +1.26 V. Predict about theformation of M^(3+)ions in solution and compare the electropositive characterof the twometals.
Answer» Solution :The negative valueof `E^(@)` for `Al^(3+)//Al` SUGGESTS that Al has a strongtendency to form`Al^(3+)`(aq) IONS. On the other hand,the positivevalue of`E^(@)`for `Tl^(3+)//Tl` suggests that Tl does not have HIGH tendency to form `Tl^(3+)` ions. Since Al can form `Al^(3+)` ions more easily than `Tl` does to form `Tl^(3+)` ions, THEREFORE Al ismore ELECTRONEGATIVITY than Tl.
