Question: find the pH of an aqueous 0.050 M carbonic acid (H2CO3) solution. Ka1 = 4.3 x 10^-7, Ka2 = 5.2 x 10^-11. find the pH of an aqueous 0.050 M carbonic acid (H2CO3) solution.

c. Upon intense muscle activity, lactic acid (pK, 3.86 at 37 °C) forms and accumulates in pH-buffered human blood. Calculate the pH in human blood after 6 mol lactic acid is released into 6 L human blood (=total lactic acid concentration in human blood). Assume that the only pH buffer in human blood is the H2CO3/HCO3- buffer couple.

8 ] 1 point A solution of carbonic acid (H2CO3) has a pH of 5.55. . If the pk, of carbonic acid is 6.35, what is the ratio of protonated to deprotonated carbonic acid molecules? Enter your answer to two places past the decimal. Type your answer... 9 1 point What is the pH of a solution that contains 20.0% acetic acid and 80.0% sodium acetate by

pH = 6.1 + log [HCO3-]/[H2CO3] What is the pH if the ratio of bicarbonate to carbonic acid is 20/1.5? Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

Which of the following species has the highest concentration at this pH: H2CO3: HCO3 - ; CO32 - ? Explain. What are the concentration ratios |CO32 - | / |HCO3 - ) and [HCO3 - ] / [H2CO3] at this pH? In the deep sea, light levels are low. and the pH is around 7.5. Suggest a reason for the lower pH at the greater ocean depth.

Question: Question Consider the reaction: CO2 + H2O <-> H2CO3 <-> H+ + HCO3 Which of the following are NOT true? the reaction goes both ways if pH decreases, HCO3- is used up to maintain homeostasis the reaction to the right is catalyzed by carbonic dehydrase increased HCO3- drives the reaction to the left the reaction to the left is catalyzed by carbonic anhydrase

Given that carbonic acid, H2CO3, has a pKa1 = 6.37 and a pKa2 = 10.33, answer the following. (a) If you wanted to make a pH 7 buffer solution starting with NaHCO3(aq), would you add 0.10 M HCl or 0.10 M NaOH? (b) If you began with 6.5 mL of 0.37 M NaHCO3, how many mL of your choice from (a) would you need to add to get a pH 7 buffer?

Using the following Ka values, calculate the pH values for each of these solutions (using 2 significant figures). [Ka for acetic acid = 1.78x105; Ka for phosphoric acid = 7.52x10 3:Ka for H2CO3 = 4.3x107] Yes! This is correct. A. A solution of 0.3 M acetic acid has a pH of 2.7 Yes! This is correct. B.

Question: Please prepare a pCpH diagram for a closed system of carbonic acid (H2CO3) after diluting 1.80 mM of the acid in water at 25℃. For this system, please indicate the concentration of bicarbonate (HCO3 2-) and carbonate (CO3 2-) at pH 8 and pH 12 from the graph and from the acid dissociation formulas given in class.
