pH Scale: Acids, bases, pH and buffers (article) | Khan Academy
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and …
The pH scale (video) | Acids and bases | Khan Academy
The pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion …
pH, pOH, and the pH scale (article) | Khan Academy
Converting [H +] to pH is a convenient way to gauge the relative acidity or basicity of a solution. The pH scale allows us to easily rank different substances by their pH value.

Properties of buffers (video) - Khan Academy
So, what is a buffer essentially? A buffer is just a solution formed from mixing a significant amount of weak acid with its conjugate weak base. The result is a solution which resists large changes …
