CALCIUM HARDNESS DETERMINATION Fill a 50 mL burette with 0.01 M EDTA solution, making sure the tip is full and free of air bubbles. Set Start volume. Add 50.00 mL of an unknown hard water solution into a 100 mL beaker. Obtain Magnetic Stirrer from Equipment menu. Place beaker on stirrer. Increase Stir from the context menu. Add 4 mL of 1.0 M Sodium Hydroxide. Add 100 mg of Murexide indicator. Titrate with the 0.01 M EDTA until the color...

Water Hardness by EDTA Titration Objective: To determine [Ca2+,MG2+] and [Mg2+] concentration in an unknown water sample A 0.0107 molarity solution of EDTA is prepared for the experiment. 25 mL of an unknown is pipetted and diluted 100 mL with distilled water and adjusted to a pH between 8 and 10 with NH4OH. A 10.00 mL portion of the diluted unknown is transferred to a 250 mL flask with 3 mL of pH 10 ammonia buffer and tiny amount of...

2. Calculate the concentration of one liter of the resulting
calcium chloride solution (assuming you started with 102.7 mg of
calcium carbonate) in units of molar and millimolar. Also calculate
the concentration in “parts-per-million as CaCO3”. (Refer to
section 13.5 of your textbook, if needed.)

5. 3. In Part 1 of the experiment (preparation of Ca²+ (aq) solution of known concentration), the volumes of water used in steps 1, 2, 3, and 5 are all approximate. Why doesn't it matter that these volumes are approximate rather than accurately measured? (Be specific.) 4.

I NEED HELP WITH THIS LAB
color marks the endpoint of the titration. We can then relate the volume of EDTA solution required to reach the endpoint to the mass of zinc present in each lozenge. Procedure: 1. Fill the buret with 0.0100 M EDTA solution. Clean any spills immediately. Run some EDTA solution out of the buret to get rid of the air bubble in the buret tip. Adjust the amount of EDTA to the 0.0 mL mark. Record...
