What happens to the buffer solution pH 7 when acid is added?
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
Why use different buffers for a range of ph?
Each buffer will only be of sufficient capacity within a pH interval of pKa+1 > pH > pKa-1 so the optimal buffer pH-range is maximum 2 units.
How do you calculate the total buffer capacity of an aqueous solution of a strong base or base at any pH?
Buffer capacity depends on the Ka of the buffer component, the concentration of the buffer (C), as well as the [H3O+]. Thus, it will beBuffer capacity = 2.3 C (Ka x [H3O+]/(Ka + [H3O+])^2The Ka will be that of the conjugate acid and [H3OP+] will be the antilog of -pH. Then just plug and chug.
What is buffer capacity and what are the factors that effect the buffer capacity?
it is defined the capability of a buffer to resist the change of pH.it can be measured quantity that how much extra acid or base , the solution can absorb before the buffer is essentially destroyed. buffer capacity of a buffer solution is determined by the sizes of actual molarities . so , a chemist must decide before making the buffer solution.
What happens in a buffer when the level of H ions in solution increase?
there will be no change .because the buffer resist change in ph.
Effect of Diluting a buffer?
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
What happens to pH when NaOH is added to buffer?
Quantity matters. If there is a lot of buffer (in terms of moles) and relatively little NaOH then the buffer will prevent any change in pH. If there is relatively more NaOH than buffer, then of course the pH will rise.
Why is buffer capacity important?
because it resists change of ph of acid and base

When does a buffer have its greatest buffer capacity?
when the capacity equals PKa where concentrations of acid and salt are the same that means Log base/acid equals zero
What factors determine the buffering capacity of a solution?
The concentration of the buffer (the higher the concentration, the larger the buffering capacity) and how close the pKa of the buffer is compared to the pH of the solution (the closer the greater the buffer capacity).See the Related Questions to the left for more information on buffers.

How temperature can effect the buffer capacity?
Buffer solutions are chemicals that react in both acidic and alkaline chemicals to neutralize them. They are often used to create a neutral solution when calibrating a pH meter. High temperatures can degrade a buffer solution, reducing its effectiveness. Ph meters are also effected by temperatures, so it is essential to follow the manufacturer's instructions about the temperatures when calibrating them,
What happens in a buffer when the level of H ions in solutions increase?
there will be no change .because the buffer resist change in ph.
What happens in a buffer when the level of H ions in the solutions increaSE?
there will be no change .because the buffer resist change in ph.
