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.
A buffer solution is designed to resist changes in pH when small amounts of acids or bases are added. It can help maintain the pH within a specific range, but it is not necessarily set to maintain a pH of 7. The specific pH range depends on the components of the buffer solution.
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.
help maintain a relatively stable pH by neutralizing the added base through a chemical reaction with the buffer components. The buffer's ability to resist changes in pH is due to the presence of both a weak acid and its conjugate base in the solution.
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.
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.
Yes, it is possible.

To make a urease solution, simply dissolve urease enzyme powder in an appropriate buffer solution of your choice, such as phosphate buffer at the desired pH. The concentration of urease in the solution will depend on the specific experiment or assay you are conducting, so adjust the concentration as needed. Remember to keep the solution cold and handle the enzyme with care to maintain its activity.
Adding more acid to a buffer solution will initially cause a slight decrease in pH as the buffer system neutralizes the added acid. However, as the acid is continually added, the buffer system may become overwhelmed, leading to a significant decrease in pH over time.
Jst keep the solution in the pH range 6 to 7 with a phosphate buffer..... Thanks, Bidya Sekhar
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
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.
A chemist might add a buffer to a solution to maintain a stable pH level, as buffers resist changes in pH by absorbing excess H+ or OH- ions. This is important when working with sensitive reactions or biological systems that require a specific pH environment to function optimally.
A buffer solution is a substance that helps maintain pH levels from changing by resisting large fluctuations in acidity or alkalinity when an acid or base is added. Buffers work by containing a weak acid and its conjugate base, which can neutralize added acids or bases to keep the solution's pH relatively stable.
