What are compounds that resist changes in pH?
A buffer resists pH change.
Describe the differences between the behavior of the buffer solution and the pure water upon the addition of alkali?
A buffer solution will resist changes in pH when an alkali is added, as it contains a weak acid and its conjugate base which can neutralize the alkali. Pure water will undergo a significant increase in pH upon addition of an alkali as there are no other components present to buffer or resist the pH change.
Do buffers resist change in pH?
Yes, buffers resist changes in pH by neutralizing added acids or bases through an equilibrium reaction. Buffers contain a weak acid and its conjugate base (or a weak base and its conjugate acid) that can absorb protons or hydroxide ions, preventing drastic changes in pH.
How buffers work?
They resist large and /or abrupt changes in pH. Made from a weak acid and it's conjugate base.
What is the role of buffers in the human body systems?
Buffers resist pH changes in cell cytoplasm, and in extracellular fluids.
Liquids that resist large changes in pH are?
buffered
What are compounds that resist changes in pH?
A buffer resists pH change.
What name is given to substance that resist changes in pH?
A substance which resists changes in pH is called a buffer.
What is the function of a buffer?
to resist drastic changes in the pH of a solution
Do buffers resist abrupt and large changes in the pH of the body by releasing or binding ions?
Yes, buffers resist abrupt changes in pH by either releasing or binding ions depending on whether the pH is increasing or decreasing. This helps maintain a relatively stable pH in the body despite external influences.

Is HCl a pH buffer?
HCl is not a pH buffer as it is a strong acid that completely dissociates in solution, leading to rapid changes in pH. Buffers consist of a weak acid and its conjugate base, which can resist changes in pH by absorbing or releasing protons.
Does a buffer always hold the pH of a solution at pH 7?
No, a buffer does not always hold the pH of a solution at pH 7. A buffer is a solution that can resist changes in pH when an acid or base is added. The actual pH at which a buffer solution can effectively resist changes depends on the specific components and their concentrations in the buffer system.
Why does the pH of an acetate buffer increases after dilution with water?
The increase in pH of an acetate buffer after dilution with water is due to the decrease in the concentration of the acetic acid and acetate ions in the solution. This decreases the buffering capacity of the solution, causing the pH to shift towards the pKa of acetic acid (4.76) as the system is no longer able to resist changes in pH as effectively.
How buffers work?
They resist large and /or abrupt changes in pH. Made from a weak acid and it's conjugate base.
Buffers resist abrupt and large changes in the pH of the body by releasing or binding ions?
Buffers in the body resist changes in pH by either accepting or donating protons. This helps to stabilize the pH of bodily fluids and prevent large fluctuations that can be harmful to cellular functions. Buffers play a crucial role in maintaining homeostasis within the body.
