Module 3 Flashcards
H2O, pH, Redox Reactions
The pH is a unit of measure indicating the concentration of …
Protons in a solution
Buffers are physiologically important because…
they help maintain pH homeostasis
A change in pH from 4 to 6 would indicate that the solution is…
100 times more basic
In oxidation-reduction reactions, the electron donor is said to be…
oxidized
In Hydrolysis…
a molecule of water is used to break a chemical bond
All electrolytes are…
Ions
Buffers tend to prevent changes in pH when___ are added to a solution
Proton donors or acceptors
Water is important for temperature homeostasis because of which physical properties…
High vaporization heat loss, and can absorb high heat wothout changing tempertures
Base
greater than 7
Acid
Less than 7
Neutral
equal to 7
T/F An acid can be described as a proton acceptor
False
T/F Oxidation-Reduction reactions are always irreversible
True
T/F H20 is a byproduct of Redox Reactions because superoxide must be converted to water to prevent cellular damage
True
T/F The lower the pH, the lower the hydrogen ion concentration
False
