Answer: HPLC-Ion Chromatography
The most popular applications of ion chromatography are determination of common anions (F-, Cl-, Br-, NO2-, NO3-, PO43-, SO42-) and cations (Na+, K+, NH4+, Mg2+, Ca2+) in water and wastewater. There are mono positive and negative ions are present, atomic spectroscopy will lead an ambigous state, uv-vis cannot differentiate between them accurately. Gas chromatography doesn't do well for same atomic mass. Only ion chromatography is best method for current situation

A soil scientist collected random soil samples from a field and
measured the dissolved organic carbon (mg/L) level of each sample.
The measurements are recorded in DissolvedOrganicCarbon.xlsx (Links
to an external site.)Links to an external site.. The researcher
would like to test if the mean dissolved organic carbon level in
the field is less than 14 mg/L. Use a significance level of
0.05.
Part 1: Which hypothesis test is appropriate for this
situation?
The difference of means, using independent
samples. ...

Hard water often contains dissolved Ca2+ and Mg2+ ions. One way
to soften water is to add phosphates. The phosphate ion forms
insoluble precipitates with calcium and magnesium ions, removing
them from solution. Suppose that a solution is 0.049 M in calcium
chloride and 0.094 M in magnesium nitrate. What mass of sodium
phosphate would have to be added to 1.4 L of this solution to
completely eliminate the hard water ions? Assume complete reaction.
