### Carbon Dioxide - Carbonic Acid Equilibriu

1. For pH 7.4, you need to have ~20x more NaHCO3 than H2CO3. An issue you need to consider is that the pK for H2CO3 is 6.3. pH 7.4 is1.1 pH units away from the pK, so you would be on the edge of.
2. See below: Warning: Long answer! H_2CO_3, or carbonic acid, is a weak acid formed from carbon dioxide reacting with water. CO_2(g) + H_2O(l) rightleftharpoons H_2CO_3 (aq) Being a weak acid, it will only partially dissociate in water, and has a dissociation constant, K_a, of 4.3 times 10^-7 according to This table. Really, carbonic acid is diprotic, meaning it can dissociate twice, so we have.
3. H2CO3 + H2O ⇌ H3O + + HCO3- HCO3- + H2O ⇌ H3O + + CO32- However, the acid-base behavior of carbonic acid depends on the different velocities of some of the reactions involved, as well as its dependence on the pH of the system. For example, at a pH below 8, the major reactions and their relative velocity are as follows

pH of H2CO3 solution = -log[2.78 x 10-4 M] = 3.56 . On your calculator (if you have a scientific one), type in 2.78 x 10-4, then press the LOG key. Hit the +/- key to convert the answer to a positive value. I'm working on pH stuff right now too. I hope this helps you! 19 0 Carbonic acid, as its name suggests, is an acid. The formula for finding pH of a substance is -log[H3O+]. The concentration of H3O+ is the same as the concentration of the acid in this case, and so all you have to do is type into your calculator: -log[0.1], which is equal to a pH of 1 conjugate base of HCl is a weak base Cl-. thus when we examine the carbonic acid, H2CO3, when it loses a proton, H+, the base formed will be a strong and resonance staballized base CO3- -. Thus it is aweak acid If the weak acid and conjugate salt are the only things in solution, the pH is determined by the ratio of acid to salt (this is the source of tables relating pK, [CO 2] and pH). You can get significant buffering out to about a 100:1 ratio, so most buffer systems will work over a total range of about 4 pH units; they work best, o

The buffering reaction is as followed: CO2 + H2O ⇌ H2CO3 ⇌ HCO3- + H3O+ The bicarbonate buffering system involves the balance of carbonic acid (H2CO3), bicarbonate ion (HCO3-), and carbon dioxide (CO2), catalyzed by the enzyme carbonic anhydrase.. Carbonic acid, a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide, dissolves in water. It plays a role in the formation of cave structures and the transport of carbon dioxide in the blood

Instructions for pH Calculator Case 1. Initial concentrations of components in a mixture are known. For each compound enter compound name (optional), concentration and Ka/Kb or pKa/pKb values. For example: CH3COOH pKa=4.76 c=0.1 HCl pKa=-10 c=0.1 Case 2. Solution is formed by mixing known volumes of solutions with known concentrations All of them stabilize pH (concentration of H+). 1. Carbonic acid (weak acid) dissociates partly bothsides: H2O + CO2 <=> H2CO3 <=> HCO3-, H+. Whatever you add, the equilibrium of this reaction shifts to one or another direction and H+ concentration of the solution (acidity) remains the same. a) If you add acid ( more H+ then), a disbalance occurs In order to maintain a normal blood pH of 7.35 - 7.45 a specific HCO3-/H2CO3 ratio is obtained by having typical concentrations of H2CO3 and HCO3- in the blood of 0.0025 M H2CO3 and 0.0025 M HCO3-. Show how to determine and calculate the value for this H2CO3/HCO3- ratio as well as the pH of this buffer solution and indicate if normal blood is acidic, basic or neutral (the Ka for carbonic acid.

Buffers in the Blood The pH of blood is 7.35 - 7.45 Changes in pH below 6.8 and above 8.0 may result in death The major buffer system in the body fluid is H2CO3/HCO3- Some CO2, the end product of cellular metabolism, is carried to the lungs for elimination, and the rest dissolves in body fluids, forming carbonic acid that dissociates to produce bicarbonate (HCO3-) and hydronium (H3O+) ions. T - pH - log K The slope for is -1; log [HA] / pH = -1 The steps for constructing the graph are: (1) Label axes (pH and -log [C]) (2) Draw a horizontal line for total concentration; (at -logCT), for the acetic acid above this will be at 2 (3) Locate system point, pH = pK and HA = A-; note that the cross over is 0.3 lo Therefore, at pH 8.5, you will have both carbonate and bicarbonate present. One simple way to make your buffer is to make two 100mM solutions, one of NaHCO 3 and one of Na 2 CO 3

The lower the pH, the more acidic a solution is. Carbon dioxide is an essential part of the carbonate buffer system 3. When carbon dioxide is dissolved in the blood, it creates a buffer composed of bicarbonate ions, HCO3- , carbonic acid, H2CO3, and carbon dioxide, CO2 2 3. All three exist in equilibrium with.

Our body will maintain pH 7.4 and pK is constant, so it can alter the bicarbonate and PaCO 2 (H2CO3). The body normally maintains the arterial pH between 7.35 to 7.45. This takes place through the buffer system of bicarbonate CO 2 enters water through interface with the atmosphere and the biological processes of organic carbon digestion and photosynthesis.: Aqueous carbon dioxide, CO 2 (aq), reacts with water forming carbonic acid, H 2 CO 3 (aq). Carbonic acid may loose protons to form bicarbonate, HCO 3 - , and carbonate, CO 3 2-.In this case the proton is liberated to the water, decreasing pH This indicates a compensatory mechanism attempted to restore a normal pH. I have not put exact limits into the calculator. For example, it will perceive respiratory acidosis as any pH < 7.35 and any CO 2 > 45 (e.g., a pH of 1 and CO 2 of 1000).
