Question 16. A volume of 200.0 mL of a carbonic acid buffer for blood plasma is prepared that contains 0.403 g of NaHCO₃ and 0.0149 g of H₂CO₃. At body temperature (37°C), the K_a of carbonic acid is 7.9 X 10^-7.

H₂CO₃(aq) + H₂O(l) ↔ HCO₃^—(aq) + H₃O⁺(aq)

a. What is the [H₂CO₃]?

b. What is the [H₃O⁺]?

c. What is the pH of the buffer?

d. Write a balanced chemical equation that shows how this buffer neutralizes added base.

A 500 mL buffer is usually prepared with 46 mM carbonic acid and 58 mM sodium bicarbonate. Unfortunately you have run out of these reagents; on hand you have the following: solid citric acid, disodium maleate (salt of maleic acid), benzylamine and hydrochloric acid. Which reagent(s), and how much of each, would you need to use to produce a 500 mL buffer with the same formal concentration and pH as the carbonic acid buffer Chemical concentration or MW Mass or...

2d. Bicarbonate does buffer the blood because carbonic acid is generated from dissolving CO2 (g) in liquid water: CO2 (g) + H2O (l) ↔ H2CO3 (aq) pKeq° = 2.52 at 37°C This reaction is catalyzed by the enzyme carbonic anhydrase. Consequently, the reaction that really represents what’s happening when bicarbonate buffers the blood is: CO₂ (g) + H₂O (l) ↔ HCO3- (aq) + H+ (aq). Calculate the equilibrium constant for this reaction (Hint: use Hess’s law and one of the...

A student dilutes 50 mL of a phosphoric acid-dihydrogen phosphate buffer solution to a final volume of 100 ml. Will the pH of the buffer change noticeably? (Use Henderson -Hasselbeck conceptually ) For the same dilution above will the buffer capacity change ? Calculations: A 50.0 mL sample of a 0.100 M phosphoric acid, H3PO4 is titrated with 0.100 M NaOH. Identify the major chemical species present and calculate the pH at these four points (first consider the titration curve)...

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 8.00 ml/kg for the distribution of blood plasma. (a) Find a...
