Thiocyanate in Human Saliva (Lab Report)

Introduction:
Including the material and the back ground of Spectrophotometric Determination of Thiocyanate in Human Saliva, with adding formulas if needed. Used KSCN Potassium Thiocyanate (Molecular Weight 97.18 g/mol) and

Experimental Procedure:
Stock solution of Potassium Thiocyanate KSCN 50ml (Distilled water and .1621g of KSCN).
Fe(NO3)3 · 9 H2O is the another solution(I will update info cuz not sure).
Result and Discussion:
used two table that found in the attache article, and the excel data that I will attached below because it shows data that I need to discuss and I will the required point and information that need to clarify.
