Chapter 10: Q16P (page 231)

Phosphate at0.01Mis one of the main buffers in blood plasma, whose pH is 7.45. Would phosphate be as useful if the plasma pH were 8.5?

Short Answer

Expert verified

As a result, at pH=8.50, phosphoric acid would be less beneficial.

Step by step solution

01

Definition of Phosphoric acid

  • Phosphoric acid (H3PO4), also known as orthophosphoric acid, is the most important oxygen acid of phosphorus and is used to generate fertiliser phosphate salts.
  • It's also employed in dental cements, albumin derivative manufacturing, and the sugar and textile sectors.

Determine the phosphate is useful if the plasma pH were 8.5

  • Phosphate with 0.01MOne of the buffers in blood plasma is concentration. It look at if the phosphate would be as effective if the plasma pH was 8.50.
  • Search at the Pg899 and look in the Table for the phosphoric acid's pKawhich is pK_{a}=7.198.
  • #c34632the amount of moles of a base or an acid required to adjust the pH of a solution by one is known as buffer capacity.
  • At pH=7.45, phosphoric acid has a high buffer capacity, while at pH=8.50, it has a low buffer capacity.
  • As a result, at pH=8.50, phosphoric acid would be less beneficial.
