55. Human blood is buffered by carbonic acid and bicarbonate ions.Alkalosis is a condition caused by excess production of bicar-bonate in the blood. A patient's blood plasma has a pH = 7.6(pKa for H2CO3 at body temperature is 6.1).MISSED THIS? Read Section 18.2; Watch KCV 18.2B, IWE 18.2, 18.3[HCO3][H2CO3]a. What is the ratio ofin the patient's blood?b. The doctor gives the patient 0.45 g of HCl intravenously toneutralize alkalosis. After treatment, the patient's blood is0.0156 M in HCO3¯ and 0.0012 M in H2CO3. If the volume ofblood in the patient's body is 5.3 L, what is its new pH?

An analytical chemist is titrating 57.7mL of a 0.2900M solution of formic acid H2CO2 with a 0.9700M solution of KOH . The pKa of formic acid is 3.74 . Calculate the pH of the acid solution after the chemist has added 7.03mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places.

How does NaC2H3O2 act as a buffer?
3 f you prepared a liter of a buffer solution to mitigate the increase in acid produced by a reaction you are studying, should the buffer you prepare have a pH less than, equal to, or greater than the pKa of the weak acid of your buffer system? Explain in three sentences or fewer.
A biochemist prepares two stocks of sodium phosphate buffer by titrating phosphoric acid with sodium hydroxide. She prepares a 0.10 M solution of sodium phosphate buffer at pH 2.15, and she prepares a 0.10 M solution of sodium phosphate buffer at pH 7.20. If she mixes 48 mL of the pH 2.15 buffer with 29 mL of the pH 7.20 buffer, what will be the pH of the resulting solution? Recall that the pKas of phosphoric acid are 2.15, 7.20, and 12.35. Enter your answer to the nearest hundredth.
Consider a buffer solution prepared by adding 0.45 mol of CH3COOK to 1.00 L of 2.00 M CH3COOH. (K₁ = 1.8 x 10-5). If 0.05 mol of HCI is added to this buffer solution the pH of the solution will drop slightly. The pH does not drastically decrease because the HCI reacts with present in the buffer solution. Select one: O a. H₂O O b. CH3COOH O C. CH3COO O d. H+
Calculate the expected pH of the buffer.
