Acid Base Reactions

Question 1

Acid base balance

Answer 1

predominantly the result of hydrogen ion concentration ([H+]) and is expressed in manageable quantities as potential hydrogen (pH).

Question 2

Regulation of acid-base balance resembles that of many other ions in two main ways:

Answer 2

o There must be a balance between intake or production of H+ and net removal from the body.
o The kidneys play a key role in regulating H+ removal from the body, as we saw in our session on ‘Renal Physiology’.

Question 3

[H+]

Answer 3

Hydrogen ion concentration

Question 4

What’s plasma and muscle ph

Answer 4

Plasma and muscle pH is maintained between 7.35-7.45 AU

Question 5

Concentration of h+ comparing to na concentration

Answer 5

Sodium concentration ([Na+]) in extracellular fluid (142 mEq/L) is about 3.5 million times greater than that of H+ (averaging 0.00004 mEq/L).

Question 6

Weak acid

Answer 6

An acid that demonstrates only a moderate tendency to dissociate.

Question 7

Conjugate base

Answer 7

What remains after the acid loses its proton (H+).

Question 8

What’s included in the buffer pair

Answer 8

Weak acid and a conjugate base

Question 9

Equation between a weak acid and a conjugate base

Answer 9

HA<-→H+ +A-

Question 10

Association reaction

Answer 10

When [H+] starts to increase, some of the dissolved A- ‘associates’ with free H+ in what is known as the association reaction, expressed as: A- +H+→HA

Question 11

Dissociation reaction

Answer 11

In the reverse dissociation reaction, dissolved HA ‘dissociates’ in response to declining [H+], releasing H+ as follows:
HA→A- + H+
