Compare the lewis structure of carbonic acid (H2CO3) and carbonate ion (CO3-2) and explain the differences....
Write a Lewis structure(s) for the carbonate ion, CO3^2-, If there are more than one resonance form, which form is stable.
One of the most important buffering systems in the biological realm is the carbonic acid (H2CO3)/carbonate ion (HCO3- ) system that maintains the pH of blood plasma to a relatively constant value. In blood at 37°C, the Ka of carbonic acid is 8x10-8. Suppose that the concentrations of the buffer components in the blood plasma are: [HCO3-] = 0.24 M and [H2CO3] = .12 M. Calculate the pH of blood.
Draw the Lewis structure for the carbonate anion CO3 ^2- and indicate which resonance structure – if any - you think will dominate in the resonance hybrid.
Compare the following: Acid 1: carbonic acid , H2CO3 Acid 2: sulfurous acid , H2SO3 Acid 3: hydrosulfuric acid , H2S What is the formula for the strongest acid ?
Calculate the pH of a solution prepared by dissolving 0.876 moles of carbonic acid (H2CO3) and 0.543 moles of sodium hydrogen carbonate (NaHCO3) in water sufficient to yield 1.00 L of solution. The Ka of carbonic acid is 4.5x10^-7. Explain answer please
Add missing charges and non-bonding electrons. A Lewis structure for the carbonate ion (CO3-) is shown, but incomplete. Complete the structure by adding in formal charges and non-bonding electrons. Then draw the other two major resonance structures that fit the octet rule. Select Draw Rings More Erase III co 0- 2 Draw major resonance structure 2. Be sure to add charges and non-bonding electrons where appropriate. Draw major resonance structure 3. Be sure to add charges and non-bonding electrons where...
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?
Classroom Activity 2: The Carbonate System When a carbonate salt, such as sodium carbonate, is placed into an acidic solution, carbonic acid (H.CO. weak acid, is formed. 1. Write the chemical formula for the carbonate ion. 2. Draw the Lewis structure for the carbonate ion. 3. How many hydrogen ions can react with the carbonate ion? 4. The chemical formula for carbonic acid is H.CO, How many K values does this acid have? 5. Starting from carbonic acid, write the...
Carbonate buffers are important in regulating the pH of blood at 7.40. If the carbonic acid concentration in a sample of blood is 0.0010 M, determine the bicarbonate ion concentration required to buffer the pH of blood at pH = 7.40. H2CO3(aq) = HCO3- (aq) + H+ (aq) Ka, = 4.3 x 10-7 27 Concentration =
