Ok, it's 1.5 mg per mL of Blood, you can reach this concentration by disolving 0.6 mg of EDTA in 10 mL of still water, then you add 100 microLitters (0.1mL) of this 6% EDTA into a glass tube. The next thing you've to do is to dry the test tube so that you'll only have 6 mg of EDTA, enough to anticoagulate exactly 4 mL of fresh complete blood. The final concentration of EDTA in the blood should be into the range of 1.25 to 1.75 mg per mL. I found this in Dacie's Haematology. karlosgb@live.com.mx

What color lab tube is used for ESR?
Lavender (EDTA) top tube. Hyperlipidemic or hyperbilirubinemic samples should not be tested. - excerpted from Bakerman's ABC's
What kind of tube is used for CBC?
It all depends on what system your using. If by tube you are referring to vaccutainers (blood sample containers) then you have to check. I know that purple top (EDTA) is for the ABC CBC machine as well as a manual blood smear since you need whole blood and EDTA minimizes any distortions.
What is the full name for te buffer?
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
What effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
Can you titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer?
yes you can, however you need the chemical coumpound name, how many grams of that chemical compound was used, and the litres that it was mixed with. for example: 2g of NaF was used to mix in a 1L solution (NaF has a molas mass of about 42g) 2g of NaF x 1 mol/42g (grams cancel and left with mols) 0.048mol/1L = 0.048mol/L conentartion
What preservatives are used in mayonnaise with what level of concentration?
EDTA
What is the purpose of standardizing EDTA in Complexometric titration?
Standardizing EDTA in complexometric titration is done to determine its exact molarity or concentration. This is important because the accuracy of the titration results depends on knowing the precise concentration of the EDTA solution being used. By standardizing EDTA, any errors in concentration can be corrected, ensuring accurate and reliable results in the titration process.
How do you calculate the concentration of EDTA in titration?
To calculate the concentration of EDTA in titration, you can use the formula: Concentration of EDTA (in mol/L) = (Volume of EDTA used in Liters x Normality of EDTA) / Volume of sample in Liters Make sure to substitute the values for the volume of EDTA used, normality of EDTA, and volume of the sample to determine the concentration.
How does EDTA and titration work?
EDTA is a chelating agent that binds to metal ions. In titration, EDTA is used to determine the concentration of metal ions in a solution by forming a complex with the metal ion. The endpoint of the titration is identified by a color change indicator or a pH meter, indicating that all metal ions have reacted with EDTA.
What is the final concentration of a edta solution if a 1l of 50x stock solution was made using 18.612g of edta mw 372.24?
The molar mass of EDTA is 372.24 g/mol. To calculate the molarity of the stock solution, you need to divide the mass of EDTA used (18.612 g) by its molar mass and then multiply by the dilution factor (50x). Finally, divide this result by the final volume (1 L) to get the final concentration in mol/L.
What are important applications of EDTA titrations?
Important applications of EDTA titrations include determining the concentration of metal ions in solution, such as calcium or magnesium in water samples, and determining water hardness. EDTA titrations are also used in the pharmaceutical industry to analyze the purity of drug compounds and in food industry to measure metal ions in food samples.
Determination of fe3 with EDTA by photometric titration?
In photometric titration of Fe3+ with EDTA, a complex is formed between Fe3+ and EDTA that prevents the absorption of light. As EDTA is added, it chelates with Fe3+ and forms a colorless complex, allowing more light to pass through. By measuring the decrease in absorbance of light as titrant is added, the concentration of Fe3+ can be determined.
What is disodium edta?
Used in solarcaine.
What are different types of EDTA titration?
Some types of EDTA titration include direct titration, back titration, complexometric titration, and chelatometric titration. These methods are commonly used to determine the concentration of metal ions in a solution by forming stable metal-EDTA complexes.
What is EDTA why it is used for treating hardness of water?
EDTA is ethylenediaminetetraacetic acid; the chemical formula is C10H16N2O8.EDTA can react with calcium and magnesium ions forming insoluble precipitates.
What concentration of should should be used for intravenous drip?
0.9
Which tube contains EDTA?
The tube containing EDTA is typically the purple-top tube. EDTA is an anticoagulant used in blood collection tubes to prevent blood clotting by binding to calcium ions.
