What must the carbonate ion ( CO3^2-) concentration be in order for precipitation to just begin when carbonate ion is added to a 2.0*10^-3 M Fe^2+ solution? Ksp of FeCO3=3.07*10^-11
The carbonate ion, CO32 can be represented by a series of three equivalent resonance forms. Show the resonance forms of CO32 including formal charges?How many valence electrons are there in the hydrogen phosphite ion, HPO32-? (a) Draw a Lewis structure that obeys the octet rule and assign formal charges to each atom. (Hint: hydrogen atom is attached to phosphorous atom). (b) Draw the structures where the formal charges are minimized. (c) How many resonance structures are there for this ion?
Compare the lewis structure of carbonic acid (H2CO3) and carbonate ion (CO3-2) and explain the differences. Please explain and Thank you! :-)
Write a Lewis structure(s) for the carbonate ion, CO3^2-, If there are more than one resonance form, which form is stable.
The carbonate ion CO3 2- has multiple resonance structures. a. Draw them and assign the hybridization to each of the atoms. b. Does the molecule shift between resonance structures or is the structure a hybrid of all of the resonance structures? Based on your answer, review your answer to part (a). c. Resonance structures represent that π electrons are delocalized through the structure via multiple overlapping p orbitals. How many unhybridized 2p orbitals does the carbonate ion have?
the hardness of water causes the disolved Ca+2 ion form magnesium carbonate, Mg CO3 which is slightly doluble solids. soaking solid magnesium carbonate in water only yeilds small amounts of free calcium ion that can be captured but still solvated using a chelating milecule called Ethylendiamineteraacetic acid or EDTA. the 2 reactions involved: 1- Mg CO3 ➡ Mg^+2 + CO^-2 keq= 6.8×10^-6 2- Mg^+2 + EDTA ^-4 ➡ MgEDTA ^-2 + CO ^-2 keq= 4.90×10^8 these reactions combine to give...

Use the coupled equilibrium expressions for the oceanic carbonate system to calculate the concentration of carbonate ion [CO3] in seawater that is in equilibrium with the atmosphere & has pH = 8.1. You will need a relevant p(CO2) pK2 8.97 K 1.07 x 10-9 pKo 1.53 K = 0.0295 pK1 5.85 K- 1.41 x 10-6 [H1[HCO3] co, Ko 0 x(CO2)p [HCO: I
