Lauren--PLEASE HELP

Analysis of Tap water (Hardness) Was analyzed by a complexometric titraion by the following equations 1 & 2 1. Ca^2+ + Mg^2+ --> Ca^2+ + Mg(Indicator) 2. Mg(Indicator) + Ca^2+ + EDTA^4- --> CaEDTA^2- + MgEDTA^2- + free indicator For the volume of titrant...

Analysis of Tap water (Hardness) 50.00 mL of tap water was transferred to a 250 mL erlenmyer flask. 10mL of NH3/NH4^+ ph 10 buffer was added to the flask, as well as 6 drops of eriochrome black T indicator. This soln was then titrated with EDTA soln(0.006...

The equations 1 & 2 were given, and I believe we are supposed to make an equation for the reaction from this i.e. add them so that: Ca^2+ + Mg^2+ + EDTA --> MgEDTS^2- + CaEDTA- So by using the given volume of titrant (EDTA=9.95 mL) we could find the mol o...

thank you so much for your help!!
