It’s nice that you mentioned how the water desalination process could remove dissolved salt and other contaminants from water in order to get fresh water. I was watching an educational show last night and it discussed about water desalination. It looks like a really convenient process and it seems there are companies nowadays that offer water desalination solutions.

In reply to El. Since by titration we can be just acknowledged about the hardness of water...and if the hardness of water is high which corresponds to high mineral content say salts of Mg ++ and Ca++ . Moreover salty water is considered to me more hard as compared to pprtable water.

In reply to Ephrem Fikadu.

EDTA(Ethylene Diamine Tetra Acetic Acid) is a weak acid having molecular mass of 372.24 g . It has pH of 8 ; since it is a secondary standard solution , it pH increases with increase in temperature. It is a complexing agent having high affinity towards Ca ++ and Mg 2+ during this titration.
Hope you got your answer.
Thanks for reading upto this line

In reply to SUBHRAKANTI DHAR. Same. Dilution with deionized water will not change the amount of chloride ions in solution. Only if you use silver nitrate solution of 0.282N instead of 0.0282, then you must multiply by 10,000 instead of 1,000.
