Using the graph given, suggest a complexometric method for determination of each component in a solution containing Hg2 +, Cd2 + and Sr2 +.
a) At pH 2, Hg2 +, Cd2 + and Sr2 +, then Hg2 + and Cd2 + at pH 4 and finally Sr2 + at pH 10 are titrated.
b) Titrate Hg2 +, Cd2 + and Sr2 + at pH 10, then Hg2 + and Cd2 + at pH 4 and finally Hg2 + at pH 2.
c) Titrate Hg2 +, Cd2 + and Sr2 + at pH 10, then Sr2 + and Cd2 + at pH 4 and finally Hg2 + at pH 2.
d) Titrate Hg2 +, Cd2 + and Sr2 + at pH 2, then Cd2 + and Sr2 + at pH 4 and finally Hg2 + at pH 10.
