Is the advanced edta mega plus a scam made by Miracle Breakthrough Labs?
All you have to do to find out for yourself is google "EDTA is a scam?" and you'll quickly find an number of web sites with solid evidence(scientific evidence)showing that EDTA nowhere meets the claims by it's pseudo scientists/supposed MDs. :p
What is the conditional formation constant for the reaction between EDTA and Ca2 plus at pH equals 10?
The conditional constant= 1.8*1010
What preservatives are used in mayonnaise with what level of concentration?
EDTA
Why titration with standard hard water is carried out?
To determine concentration of EDTA.
How many meters are in 600cm?
1 cm is .01m so 600cm*.01m = 6m =] -ray
What concentration of EDTA should be used for anticoagulation?
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 is a meter in cm?
.01m = 1cm
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 mass of the EDTA used to prepare 1L oi solution is 18.612g. The formula mass is 372.24 g/mol. Therefore concentration of the 50x solution is: 18.612 g 1 mol ----------- x --------- = 0.050000 mol/L = 50.000 mM 1L 372.24 g
What are different types of EDTA titration?
1. Direct Titration In direct titration, you simply add an indicator to the solution of the metal ion and titrate with EDTA. Before starting the titration,it is needed to check that the pH of the solution to obtain a good formation constant value and on the other hand indicator colour change as well. 2.Indiract titration EDTA can be used as titrant for anions. Anions can be precipitated with suitable metal ion. Filter and wash the ppt with proper solution. Then boil in excess EDTA to complex metal ion(ppt). Back titrate to determine how much metal ion you had. 3.Back Titration In a back titration an excess of EDTA is added to the metal ion solution, and the excess EDTA is titrated with a known concentration of a second metal ion. The second metal ion must form a weaker complex with EDTA than the analyte ion so the second metal does not displace the analyte ion from its complex with EDTA. 4.Displacement titration Here the analyte is treated with an excess of a second metal bound to EDTA. The analyte ion displaces the second metal from the EDTA complex, and then the second metal is titrated with EDTA.
How do you calculate the concentration of EDTA in titration?
in order to titrate a sample of solution, lets take an example. If we have a solution of 1.569 mg of Coso4, which has a (155.0g/mol ratio) per mill. A question may ask us to find the volume of Edta needed of titrate an aliqout of this solution. So lets take a random number of 0.007840 M EDTA and be asked to titrate A 25.00ML Aliqout of this solution. How do we find the volume of EDTA needed.....? well first we use the numbers given, 1.569 mg CoSo4/ ml x (1g/1000mg)(1molcoso4/155.0g)(1molEDTA/1mol CoSo4) calculating this out should give 1.012 x 10 ^-5 mol of EDTA per ml. we then multuply the moles of EDTA which react with 1.569 ml of COso4 by 25.00 ml 1.012x10^-5 mol edta (25.00ml)= 2.531 x 10^-4 mol of edta. This is the amount of moles in the new solution. Now we need to find the amount of moles per liter of the specific concentration of EDTA. so we multiply 2.531x10^-4 mol edta x (1L/0.007840 mol) to give 0.03228 Liters of 32.28 ml .
What is the length 5.000 e-01m?
6
Why EDTA is not dissolved in water?
EDTA is soluble in water.
What is the basicity of EDTA?
the basicity of EDTA is 4
What is EDTA whole blood?
EDTA whole blood is whole blood that has been drawn into a tube with EDTA in it. The EDTA is added to transport samples and prevents the blood from clotting.
