Acid-Base Flashcards
In aqueous solutions H+ usually becomes
H3O+
Are H+ ions in greater abundance than other electroyltes in the body?
No. There are a lot fewer H+
Are H+ ions highly reactive?
YES
Should H+ be kept constant in the body?
YES
Do ph and [H+] vary linearly or exponentially?
exponentially
the velocity of a reaction is proportional to what?
the reactant’s product concentrations
pH equation
pH = pKa + log (base/acid)
What is a buffer?
a compound that can accept or donate a proton to minimize pH changes
What is in a buffer solution?
weak acid, and its conjugate base
What is the first line of defense to prevent major changes in pH in the blood?
Blood buffers
What is isohydric principle?
multiple buffers in solution are in equilibrium. so if you know one system you can predict the changes in the other systems
ionic composition of bodily fluids are maintained within NARROW limits: true or false
true. a small change in pH can have drastic effects
What 3 systems help regulate pH and H+ in bodily fluids?
1) Chemical buffers (manage imbalance)
2) Lungs
3) Kidneys
How do the kidneys and lungs help regulate pH?
they try to correct pH by changing ventilation or renal function
pH equation with lungs and kidneys
pH = pKa + log (renal function/ventilation)
