what will be the new pH of a 100 lt solution if 1 lt buffer solution of 5 pH is added to it
A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added to it. It is made up of a weak acid and its conjugate base, or a weak base and its conjugate acid.
A buffer solution maintains a constant pH by having the weak acid or base react with any added acid or base, preventing a significant change in the concentration of hydrogen ions (H+) or hydroxide ions (OH-) in the solution.
The pH range of a buffer solution depends on the strength of the weak acid or base used. Generally, a buffer solution can maintain a pH within one unit of its pKa (acid) or pKb (base) value. For example, a buffer solution with a pKa of 4 can maintain a pH between 3 and 5.
The pH of a buffer solution can be calculated using the Henderson-Hasselbalch equation: pH = pKa + log([conjugate base]/[weak acid]). Alternatively, pH can be determined experimentally by measuring the concentrations of the weak acid and its conjugate base and using a pH meter.
Buffer solutions are important in scientific research because they help maintain a stable pH, which is crucial for many biological and chemical processes. They are also used to calibrate and standardize pH meters, and to control the pH in experiments and reactions.
