14. Repeat steps 5-8. RESULTS ANALYSIS 1. Calculate the average volume of EDTA used from your titrations 2. Calculate the moles of EDTA required to complex the Ca²+ ions in your samples 3. Calculate the concentration of Ca²+ ions in your samples (mol/L) taking into consideration that Ca2+: EDTA binding ratio is 1:1. Note: Remember to take into consideration the dilution factors of your calcium ion solutions.
