Hello house, I need assistance on how to plot the Chadha diagram in MS excel or any suitable and available software. Thanks
Start by converting your anion and cation concentrations to milliequivalent percentages.
Create 4 excel columns 1 each for HCO3 +CO3(weak acid anions), Cl+ SO4 (strong acid anions), Ca+ Mg and Na + K
Then create 2 additional columns for
1.(HCO3+CO3)-(Cl+SO4)
2. (Ca+Mg)-(Na+K)
Plot a cross plot with 1 above on the vertical axis and 2 on the horizontal axis.
You can do this with excel but origin 8 will give you a better result
I hope this helps.
