A buffer is supposed to keep the pH of a solution from fluctuating too much. It helps keep the pH more-or-less consistent. Whether it keeps the solution neutral, it doesn't have to be neutral. You can make a solution be whatever pH you want, but different solutions and pHs require different approaches.

Is the buffer supposed to keep the pH of a solution at 7?
Some buffer solutions maintain pH at 7, but others have different pH values. It is common to have buffers with pH values of 4, 7, and 10 for calibrating pH meters, for example.
Why might a chemist add a buffer to a solution?
The buffer can keep the pH stable when small amounts of acid or base are added. - NOVA
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.
A substance that helps to keep a stable pH in a solution is called a?
A substance that helps to maintain a specific pH is called a "Buffer" it can be either acidic or alkaline depending on the purpose and what needs to be buffered.
What are pH electrode storage solution and pH 7.0 buffer and for what are they used?
The buffer solution is used to calibrate the meter. Usually two buffer solutions are used to do this. One is close to the range of the sample that will be measured, like the 7.0 buffer that you mention could be used for aquarium water. The other solution would be more acidic, like a 4.0 buffer solution. The process is to calibrate in one solution, rinse the probe, then calibrate in the other solution. This back and forth is done until the meter is reading the desired buffer and is stable. In other words, you would finish with the 7.0 buffer solution when it is reading exactly 7.0 PH, with no further adjustments after switching from the 4.0 solution. The probe should be rinsed with PH neutral DI water and shaken dry between each between each measurement so that solutions are not mixed. The storage solution is used to store the glass probe for long periods of time. A few drops of storage solution should be dripped into the probe cap before replacing it for storage. The storage solution is just a buffer that has some anti-bacterial additives to keep stuff from growing in it. The calibration buffer can be used for short term storage though. The glass probe should NEVER be allowed to dry out for long periods and should be rinsed with DI water before storage. It should NOT be stored in DI water though. Only buffer solution or storage solution should be used.

How you can do stability of Ranitidine infusion?
Jst keep the solution in the pH range 6 to 7 with a phosphate buffer..... Thanks, Bidya Sekhar
How do you prepare calcium buffer?
This might not be the best answer but, preparing a buffer solution allows one to keep the pH value the same when small amounts of acids or bases are added. Buffer solutions resist change in pH. Source: My Chemistry teacher's PowerPoint
What is the role of a buffer?
Limit the pH....
What is a chemical buffer?
A Chemical which resists changes in pH.
How does a buffer keep a solution from becoming too acidic?
Human blood normally has a pH of about 7.4.Certain chemical reactions within your cells can lead to an increase in the amount of H+ ions.When these ions move into the blood,buffers take up some of them,preventing the blood from becoming acidic enough to endanger cell function.
