A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
<h3>What is a buffer?</h3>
A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
<h3>What is pH?</h3>
The pH of a solution is the negative logarithm to base 10 of yhe hydrogen ion concentration of the solution.
Solutions of low pH have high concentration of hydrogen ions while solutions of high pH have high hydrogen ion concentration.

Answer: The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
Hope this helps............ Stay safe and have a Merry Christmas!!!!!!! :D
Answer:
The answer is "5.18
".
Explanation:
It's a question of chemistry. Therefore, the following solution is provided:
We will first determine the solution's pOH. The following can possible:
The concentration of Hydroxide ion ![[OH^{-}] = 1.5\times 10^{-9}\ M](https://tex.z-dn.net/?f=%5BOH%5E%7B-%7D%5D%20%3D%201.5%5Ctimes%2010%5E%7B-9%7D%5C%20M)
![pOH =?\\\\pOH = -\log [OH^{-}]\\\\pOH = -\log 1.5\times 10^{-9}\\\\pOH = 8.82\\\\](https://tex.z-dn.net/?f=pOH%20%3D%3F%5C%5C%5C%5CpOH%20%3D%20-%5Clog%20%5BOH%5E%7B-%7D%5D%5C%5C%5C%5CpOH%20%3D%20-%5Clog%201.5%5Ctimes%2010%5E%7B-9%7D%5C%5C%5C%5CpOH%20%3D%208.82%5C%5C%5C%5C)
Furthermore, the pH of the solution shall be established. It was provided as follows:

When collecting all the like terms:
Therefore, the solution of pH is 5.18.
