The total concentration of Ca and Mg* in a sample of hard water was determined by titrating a 0.125 L sample of the water with a solution of EDTA, The EDTA chelates the Ca+ and Mg+. Ca (aq) + EDTA (aq) Mg2 (aq) + EDTA+ (aq) Ca(EDTA) (aq) Mg(EDTA)?-(aq) The sample required 34.9 ml of 0.0360 M EDTA solution to reach the end point in the titration. A second 0.125 L sample was then treated with sulfate ions to precipitate Ca as calcium sulfate. The Mg* was then titrated with 23.5 ml. of 0.0360 M EDTA*. What is the concentration of Mg* in the sample of hard water in milligrams per liter (mg/L). [Mg1= mg/L

The amount of calcium in physiologic fluids can be determined by a complexometric titration with EDTA. In one such analysis, a 0.100-mL sample of blood serum was made basic by adding 2 drops of NaOH and titrated with 0.00528 M EDTA, requiring 0.233 mL to reach the end point. Report the concentration of calcium in the sample as miligrams of Ca per 100 mL. (Ca = 40.078 amu).
One of the buffers that can be used for running an agarose gel is 1x TBE (tris borate EDTA) buffer. The recipe for 1x TBE is: • 0.13 M tris • 45 mM boric acid • 2.5 mM EDTA How will you make 1 L of this buffer from 1M stock solutions of tris, boric acid, and EDTA? Put your answers in the blanks. To make 1 Lof this buffer, I would need: L of 1 M Tris ml of 1 M boric acid ml of 1 M EDTA Then, these will be topped up with distilled water in a volumetric flask up to the 1L mark.
