Acid Base

Question 1

pH

Answer 1

potential or power of hydrogen
Scale identifies acidity/basic of solution

Question 2

Is PH a negative or positive logarithm

Answer 2

Negative

Question 3

when hydrogen concentration increases, pH __

Answer 3

Decreases, more acidic

Question 4

when hydrogen concentration decreases, PH __

Answer 4

Increases, more basic

Question 5

what is the most acidic substance in our body?

Answer 5

Stomach acid

Question 6

T/F acids have more hydrogen ions and can donate them

Answer 6

True

Question 7

do bases have more or less hydrogen ions?

Answer 7

Less, they accept hydrogen ions and give up hydroxide ions

Question 8

hydrogen

Answer 8

Helps maintain cell membranes, and enzyme activity

component of water and hydration

Helps in energy production

Question 9

what is a neutral pH?

Answer 9

7

When hydrogen ions equal hydroxide ions

Question 10

what is the normal range of pH for the body?

Answer 10

7.35-7.45

Measured in serum blood

Question 11

T/F PH is the same throughout the whole body

Answer 11

False

Question 12

What occurs is HCl is outside of the stomach?

Answer 12

Damage can occur

Question 13

which part of the stomach has a defense mechanism to neutralize the acid?

Answer 13

Duodenum

Question 14

what does the LES prevent with stomach acid?

Answer 14

Backflow of gastric acid into the esophagus

Question 15

what electrolytes are affected by pH range?

Answer 15

Sodium
Potassium
Chloride

Question 16

oxyhemoglobin dissociation curve

Answer 16

More acidic solutions, give up, hemoglobin more at tissues

More alkalotic solutions don’t give up hemoglobin and struggle to oxygenate

Question 17

volatile acids

Answer 17

Can be converted to gas
Excreted by lungs
Carbonic acid H2CO3

Question 18

non-volatile acids

Answer 18

Lactic, phosphoric, sulfuric, acetoaecitic, beta hydroxybutyric acid

Not dissolved, or converted to gas

Eliminated by kidney

Question 19

what is the exception to nonvolatile acids?

Answer 19

Lactic acid

It is metabolized by the body – liver and kidney

Question 20

T/F the body produces more bases than acids

Answer 20

False

Question 21

is it more difficult to correct an acidic pH or alkalotic pH?

Answer 21

Alkalotic

Question 22

what value characterizes, alkalosis hypocapnia

Answer 22

7.0

Question 23

what pH value characterizes acidosis hypercapnia

Answer 23

7.8
