In a water Hardness complexometric micro-titration, EDTA was used as a standard. The formula is : Ca ^2+ Y^4- - CaY^2 where (Y is EDTA) Suppose the EDTA used was not as dry as it should have been a. Would [EDTA] in the EDTA solution be higher or lower than the actual value? b. Would the [Ca] determined in the unknown be higher or lower than the actual value?

i am insure what are the correct answers for this one
EDTA Titration 1. EDTA (cthylenediaminetetraacetic acid) is the most widely used metal chelator in analytical chemistry, which forms strong 1:1 complexes with most metal ions. Water hardness can be determined by titrating Ca, Mg and other metal ions with EDTA. During the titration, ammonium-ammonia chloride buffer is often used. Which of the following descriptions about the function of ammonium-ammonia chloride is/are correct? (a) To react with EDTA To form...

Question 4 (1 point) An indirect EDTA titration was performed on a water sample to determine the sulfate content. First, the analyst measured the hardness of the water by directly titrating a 50 mL aliquot with 0.00515 M EDTA. If it took 14.40 mL of the EDTA solution to reach the endpoint, what is the hardness, or concentration (in M) of metals in the water sample?

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...

1. Using EDTA as the titrant and a free metal in solution is called a direct titration. This can be measured using an indicator that changes color when the metal is no longer in solution. What the other types of EDTA titrations that can be done and why would you choose to do one of are those? 2. What is the formation constant for calcium with EDTA? Are there any challenges with doing a direct titration with Ca2? If so...
