EDTA binds metal ions to form complex ions (see Problem 19.142 ) , so it is used to determine the concentrations of metal ions in solution: $$ \mathrm{M}^{n+}(a q)+\mathrm{EDTA}^{4-}(a q) \longrightarrow \mathrm{MEDTA}^{n-4}(a q) $$ A $50.0-\mathrm{mL}$ sample of $0.048 M \mathrm{Co}^{2+}$ is titrated with $0.050 M$ EDTA $^{4-}$. Find $\left[\mathrm{Co}^{2+}\right]$ and $\left[\mathrm{EDTA}^{4-}\right]$ after addition of (a) $25.0 \mathrm{~mL}$ and $(b) 75.0 m L$ of $E D T A^{4-}\left(\log K_{f}\right.$ of $\left.C o E D T A^{2-}=16.31\right)$
As we know that e. P. A. Age C two, h. 4 and CH two see or or minus all too. So It has six positions. It has six body since have level for have labeled but attachment at central metal atom, attachment at central mental letter. So option B. H. Correct answer for this problem.
Chinese solution when directed with stool and avoided give some right sector own additional access this compound. So could you inform general which hard place here's the correct terms.
In this problem, we can say that yellow solution yellow solution is your pain. Yellow solution Is your pain due to oxidation due to oxidation of see A three plus to c r 04 two minus iron on acidification, C r 04 to minus irons, changes to change to orange color, changed to orange colored CR 207 to minus items. So according to the option, option A is correct.
Hello, everyone. I hope all's well today I will be helping you with the fifth problem of the chapter 47 problems up. And this question is asking, Ah, what chemical? What chemical binds calcium and magnesium when e p a right. So, um when, like basically what e. T. Is is if it was if the egg cell was treated with e d. T A. So you have a theocracy. Normal reaction would be blocked, which is false. And the nea bead, the fusion of sperm and egg nuclei, would be blocked, which is not true. And then you have see the fast block to Polly Spur me would not occur, which is not true either. And then he indeed the fertilisation envelope would not form, which is true. So that's basically what would happen. So the fertilisation envelope would not true in the egg was treated with Edie with e d. T. A. And that wouldn't make a chemical that binds calcium and magnesium ions to make the fertilisation envelope, not form. So I hope you found this helpful and I hope you have a great day. Thank you. Thanks
