What is the molar concentration of EDTA?

0.0149 M
What is the molarity of the EDTA? = 0.0149 M EDTA Page 2 2 3.

How many moles are in EDTA?

Each mL EDTA used = 0.00001 moles CaCO3:0.001 L x 0.01 mol EDTA/L = 0.00001 moles EDTA = moles Ca or CaCO3.

How do you calculate normality of EDTA?

  1. You can use this formular, conc in g/dm3 =molar mass/valency * normality.
  2. The valency of EDTA is 4.
  3. Molar mass of EDTA is 294.
  4. Normality is 1.
  5. Substitute the above parameters in to the formulae.
  6. Conc in g/dm3 = 294/4 *1=73.5.
  7. Dry some quantity of EDTA and weight exactly 73.5g.

What is the molarity of Ca2+?

AS the name says on the tin, the molarity of calcium ion is 2.5⋅mol⋅L−1 ….

How do you calculate percent molarity?

To convert from \% solution to molarity, multiply the \% solution by 10 to express the percent solution grams/L, then divide by the formula weight.

Is molarity and normality of EDTA same?

1 metal ion is complexed by 1 EDTA molecule, or 1 mole of metal ions react with 1 mole of EDTA. Therefore, just because you asked, molarity and normality are the same.

What type of ligand is EDTA?

hexadentate ligand
EDTA is a hexadentate ligand.

How do you calculate the number of moles of EDTA and Zn2+?

Since Zn2+ reacts with EDTA in a 1:1 mole ratio the moles of EDTA will be equal to the moles of Zn2+. For a solution, moles can be determined by multiplying molarity by volume. mol EDTA = mol Zn2+ MEDTAVEDTA = MZn2+VZn2+ rearranging the equation above we get: MEDTA= MZn2+VZn2+/ VEDTA 2.

How do you calculate the volume of EDTA in hard water?

Get the volume of EDTA from your titration data, use the average concentration calculated above and the volume of hard water used. Total water hardness = (Ca + Mg) Volume Mol EDTA (L) EDTA 1 mol 100 g CaCO3 CaCO3 1000 mg g 1 L hard water titrated L EDTA 1 mol 1 mol 4.

What is the titration of EDTA solution of unknown molarity?

An EDTA solution of unknown molarity was standardized by titration of 10.00 mL (0.01000 L)

How can I increase the solubility of EDTA solution?

This means that EDTA limits its own solubility. To get round this problem place a pH probe in the solution (make sure the solution is being stirred) and as the pH drops (the solution becomes more acidic) carefully add pellets of NaOH to bring the solution back to 7 – or the pH for the EDTA solution if it is specified (which it often is).
