Week 11 Measured the absorbance of the "contaminated water" and gave a reading of 0.714A [Figure 3]. Inserted the measured absorbance (y-value) into the concentration vs absorbance graph equation y=0.0019x+0.001 [Figure 2], to find the concentration (x-value) of the Ni+2 ions. The concentration was determined to be 375.263 mM ..

[Figure 4 ]. How the density of sulfonate groups per gram of resin was determined. Week 10 To neutralise the amberlite solution, a small amount of Naoh was poured from the burette into the beaker during the titration. This process was repeated, with the volume of Naoh added and the pH value of the solution recorded after 5-10 minutes [Figure 4]. A graph of pH vs. volume of Naoh was used to generate the equation y=0.108x + 4.7072 [Figure 5]. Kezia Thayaparan.
