Explain your observations in terms of the strength of IMFA present in each condition.Explain why ionic attractions are weaker in media with high dielectric constants, e. g.,water and aqueous buffers.How can the matrix effects affect the determination of Calcium in seawater by using AAS?
- What part does adsorption play in froth floatation for the concentration of sulphide ores and heterogeneous catalysis?Why is it necessary to buffer the solution to a pH between 10 and 12 during the complexometric determination of magnesium using EDTA?Sometimes it is not possible to indicate the end point of a titration.a) How can one proceed then and what is the name of the type of titration that can be performed? Briefly describe. An example in which this method can be used is in the determination of mercury, which forms strong complexes with EDTA, but for which there is no suitable indicator that can indicate the end point. b) You are given the task of determining the Hg2 + concentration in a sample solution? After adding an excess of EDTA, the sample solution is titrated with a magnesium solution. 20.00 ml of a 0.0452 M EDTA solution was added to 30.00 ml of sample solutionThe excess EDTA was determined by adding 0.0500 M Mg 2+ solution, consuming 4.37 ml to the end point.
