How do you calculate concentrations of both acid and base in a buffer solution when only given pH value example pH 7.5?

pH = - log [H+]
Substitute and solve for [H+]:
7.5 = - log [H+] = 3.16E-8
That is the concentration of H+ ions. Depending on the acid, you calculate concentration of the acid based on this.
Kw (dissociation constant) for water = 10^-14
Kw = [H+]*[OH-]
Substitute and solve for the concentration of OH- = 3.16E-7
Depending on the base, you calculate the concentration of the base from this.

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.
What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
What can destroy buffer solution?
The buffer solution is destroyed if the amount of acid or base that can be absorbed is exceded.
Does a buffer always hold the pH of a solution at pH 7?
No. Many buffer solutions are mildly acidic or basic. Human blood, for example, is buffered a a mildly basic pH of 7.4

What is pseudo buffer?
a solution which does not fulfills the property of a buffer solution but act as buffer solution.
Buffers tend to prevent dramatic changes in the pH when are added to a solution?
Buffer solutions tend to prevent dramatic changes in the pH of a solution when a weak acid and its conjugate base are added. An example of a buffer solution is blood.
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
How do you make urease solution?
you can prepare 20nM sodium phosphate buffer pH7.0. calculate mass of enzyme and dilute in volume buffer to reach concentration you want. good luck
What is sorensens buffer?
Phosphate buffered saline is a buffer solution commonly used in biological research. It is a water-based salt solution containing sodium phosphate, sodium chloride and, in some formulations, potassium chloride and potassium phosphate. The osmolarity and ion concentrations of the solutions match those of the human body.
What can destroy buffer solution?
The buffer solution is destroyed if the amount of acid or base that can be absorbed is exceded.
What is TNE buffer?
tris, EDTA (TE solution) and NaCl, TNE buffer is a buffer solution used in molecular biology, especially for DNA and RNA
Which pairs of substance will form a buffer when mixed in equal concentrations?
CHOOH and NaCHOO
What is the purpose of buffer?
Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.
When a base is added to a buffer solution the buffer will?
donate H+ ions
Can be mixed in a solution with H2CO3 to make a buffer?
H2CO3 is not used as buffer.
