Determination of water hardness (titration)

This is the classic method to determine the total water hardness over a titration with EDTA solution.

I did something like that for the calculation of calcium content in a past job XD
One note, pipets are calibrated for the liquid to flow out under gravity with means that this small amount that you blew out from it, should stay in the pipette for it to measure 50 mL, otherwise you add a bit over 50 mL, with is probably a source of a bit error (hardness measured by you would be higher than it is in sample). Besides that, it is a very good video!

how do i prepare the buffer solution? i am also wondering why a ph11 solution is used instead of the more common ph 10.

Haven't heard from you in decades! Great video

Thank you, very nice. I was hoping to find a simpler method as I want to determine how often to run a water regeneration cycle for a water softener but this was very informative and well presented.

Happy to see your channel active again.

Nice, straightforward explanation of water hardness titration. Here in Hungary we also use dH.

why you don't adding the volume of buffer solution when you calculate the conc. of sample

Well, that looks familiar somehow... 😉
I hope this topic resonates better on your channel than mine...

Why wasn't magnesium complexonate used to shorten the sluggish color change?

P.S.: The lime soap should urgently be removed from the tap... 🧐
