ANSWER:Step 1 of 4
Complexometric titrations:
Complexometric titrations are used for the analysis of cations using complex-forming reagents. Metal ions are lewis acids.
The reagent donates an unshared electron pair to the metal forming a coordinate covalent bond. The product is a coordination complex which is the basis of complexometric titrations.
Chelating agents form more stable coordination complexes. The most common chelating agents are polyamine carboxylic acids.
