What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
What is a chemical compound that helps control the pH of a solution by adding or removing hydrogen ions is a(n)?
Buffer
By what three methods is Hydrogen concentration in body fluids regulated?
pH is regulated generally in the stomach, when food is broken down. Acids are introduced to dissolve food and i think then bile is introduced to neutralize the acid, so you don't get eaten from the inside out. Which would be unfortunate.
What makes egg whites a good buffer?
Protein in egg whites is composed of amino acids. These amino acids can accept and donate hydrogen ions, which makes the protein an excellent buffer.
At what pH is a buffer effective?
buffers help resist change in pH. In our bodies the normal pH is 7.4 which is slightly basic. If for some reason there are excess hydrogen ions in our bodies, the pH will drop and a buffer in the body will counteract this. For example bicarbonate, an important buffer in our bodies, will release bicarbonate ions that will combine with the hydrogen ions forming carbonic acid. Therefore the blood will not decrease in pH.
What two factors are involved in determining the exact pH of a buffer?
The molarity of the buffer and the hydrogen concentration of the buffer.
What are the substance that can take up or release hydrogen ions into solution as hydrogen concentration of solution changes?
A buffer.
What is a weak acid or base that combines reversibly with hydrogen ions?
Buffer
What best describes a buffer?
A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not changeA buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
What is the buffer capacity of a solution of a strong acid directly proportional to?
It is directly proportional to the concentration of hydrogen ions. Buffer capacity = 2.303 x [H3O+]
What substance would you add to NaHCO3(aq) to form a buffer solution?
Sodium carbonate and and sodium hydrogen carbonate form a buffer solution.
The name given to a chemical system that prevent changes in hydrogen ion concentration?
A buffer
What are the three mechanisms of hydrogen ion removal?
The three mechanisms of hydrogen removal are the Bicarbonate buffer system, the respiratory system and kidney function.
The buffer recommended for making up the tryptic solution is ammonium hydrogen carbonate what are the advantages of using this buffer Please give referece?
plz reply to diz question
Why does a buffer solution will change in pH upon addition of acid or base?
Buffering compounds are weakly ionised, addition of hydrogen or hydroxide ions (in modest amounts), shift the degree of ionisation of the buffer which produces an increase or decrease in the hydrogen or hydroxide ions provided by the buffer itself. This change in ionisation of the buffering compound approximately compensates for the addition.
What is the dissolution of sodium hydrogen carbonate?
I guess it would be NaOH and CO2. This explains why it is an alkaline buffer
What prevents rapid changes in pH by taking up either hydrogen or hydroxide ions?
a buffer
