Answer the following questions. 1) The 40 mg/L Fe stock solution was prepared with iron (II) ammonium sulfate hexahystoate (Fe(NH.):(SO.):(H;O)] rather than with iron (II) chloride [FeCl:). What is the reason of this choice?
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Answer the following questions.
1) The 40 mg/L Fe stock solution was prepared with iron (II) ammonium sulfate hesahystoate
[Fe(NH.):(SO.):(H;O)«] rather than with iron (II) chloride [FeCl:). What is the reason of this
choice?
2) For convenience, several glass or quartz cells are generally used spectrophotometrie analyses;
these cells should be "matched" with regard to their.optical properties.
a) Why they should match with each other?
b) Suppose one of the cells has a light path that is slightly longer than the usual 1.00 cm.
How would this affect the results of an analysis if the defect was not recognized?
c) Explain how the "unmatched' cell problem can be solved?
3) Draw the scheme of single bcam spectrophotometer and state the function of each
