SUMMARY
The discussion centers on calculating the concentration of calcium (Ca) in an unknown solution using EDTA titration. The user has titrated 25 ml of the unknown solution with 2.3 ml of 0.01 M EDTA, establishing a 1:1 reaction ratio between Ca and EDTA. To find the concentration of Ca in ppm, the user should first calculate the moles of EDTA used, then determine the moles of Ca, and finally convert this value to ppm based on the volume of the unknown solution.
