∙ 11y agoBuffers resist a change in the pH of a solution when acid or alkali is added to it.
Buffers are very useful in the blood, where it is very important for pH to stay the same (consider the number of enzyme catalysed reactions in the body!). Hence buffers are responsible for maintainging internal pH conditions.

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 physiologically important buffers?
An important physiological buffer is the Digestive System's Bicarbonate Buffer System: CO2 + H2O = H2CO3 = H+ + HCO3- The bicarbonate ion (HCO3-) is made by the pancreas. This is one of the pancrea's many exocrine functions. The bicarbonate helps to counteract the HCl released into the stomach thus maintaining the pH balanced.
What is the difference between a concentrated buffer and a diluted buffer?
The concentration.
What are the three buffer systems?
the three buffer systems are NaHC03 The 2 other buffer systems are H2C03 and HC03 . THANK YOU !
What is the principle buffer in the body?
A buffer is something that regulates or maintains the pH in the body. In the human body, carbonate is the main buffer in the blood and phosphate is the main buffer within cells.
What are the functions of buffer protein?
Maintaining pH
What are the two major functions of loading buffer?
To prevent sudden changes in chemical compound and to stabilize
Why scanf functions is not used to read a line of text?
Because it is not safe. Scanf puts the data into a buffer. There is no size checking so the data may be larger than the buffer causing a buffer overrun with undefined (usually bad but always undesirable) behavior.
How do you make pH 9 buffer solution?
You can create a ph 9 buffer solution by mixing together a slightly stronger acid and a base, as the acid will override the bases basic functions and great an acidic solution.
When a base is added to a buffered solution, the buffer will?
When small amounts of acid or base are added to a buffer solution, the buffer functions to keep the pH from changing.
How do you fix buffer overflow?
The problem with buffers is that you need to keep track of the amount of memory physically allocated to the buffer. This means a buffer has at least two variables: a reference to the allocation and its size. If the buffer size is constant it is obviously easier to keep track of its length but if it is variable you must ensure the size variable is kept in sync with the actual buffer length. The easiest way to keep track of buffer lengths is to store the buffer and its length in a structure: struct data { char * buffer; int length; }; You still have to ensure the length is kept in sync with the buffer, but now the two can be treated as being a single entity, making it much easier to pass buffers into and out of functions. However, a better approach is to use object-oriented programming to encapsulate the buffer and its length, thus hiding the details of the representation: std::vector<char> buffer; You no longer have to keep track of the length because that is encapsulated within the vector. Every time you push/pop values, the size is incremented or decremented accordingly. All memory management is also handled by the vector, so new memory is allocated as and when required, and the size is adjusted accordingly. All you have to do is rewrite your functions to make use of a vector rather than a buffer.
What is pinned buffer in oracle?
The buffer is in used is called as pinned buffer
What do you mean by voltage buffer?
A voltage buffer is a circuit that will buffer a source from an output.
A solution that is resistant to change in pH?
Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
Is a chemical or combination of chemicals that keeps pH within normal range?
A buffer. just got the answer correct on a bio exam
Is HCl a pH buffer?
No, it is not a buffer.
What is buffer P2?
The composition of Buffer P2 is:200 mM NaOH1% SDS (w/v)Buffer P2 is the lysis buffer
