Acid Base Flashcards
pH
potential or power of hydrogen
Scale identifies acidity/basic of solution
Is PH a negative or positive logarithm
Negative
when hydrogen concentration increases, pH __
Decreases, more acidic
when hydrogen concentration decreases, PH __
Increases, more basic
what is the most acidic substance in our body?
Stomach acid
T/F acids have more hydrogen ions and can donate them
True
do bases have more or less hydrogen ions?
Less, they accept hydrogen ions and give up hydroxide ions
hydrogen
Helps maintain cell membranes, and enzyme activity
component of water and hydration
Helps in energy production
what is a neutral pH?
7
When hydrogen ions equal hydroxide ions
what is the normal range of pH for the body?
7.35-7.45
Measured in serum blood
T/F PH is the same throughout the whole body
False
What occurs is HCl is outside of the stomach?
Damage can occur
which part of the stomach has a defense mechanism to neutralize the acid?
Duodenum
what does the LES prevent with stomach acid?
Backflow of gastric acid into the esophagus
what electrolytes are affected by pH range?
Sodium
Potassium
Chloride
oxyhemoglobin dissociation curve
More acidic solutions, give up, hemoglobin more at tissues
More alkalotic solutions don’t give up hemoglobin and struggle to oxygenate
volatile acids
Can be converted to gas
Excreted by lungs
Carbonic acid H2CO3
non-volatile acids
Lactic, phosphoric, sulfuric, acetoaecitic, beta hydroxybutyric acid
Not dissolved, or converted to gas
Eliminated by kidney
what is the exception to nonvolatile acids?
Lactic acid
It is metabolized by the body – liver and kidney
T/F the body produces more bases than acids
False
is it more difficult to correct an acidic pH or alkalotic pH?
Alkalotic
what value characterizes, alkalosis hypocapnia
7.0
what pH value characterizes acidosis hypercapnia
7.8
