When a strong base is added, the acid present in the buffer neutralizes the hydroxide ions; when a strong acid is added the base present in the buffer neutralises the hydronium ions. To help them visualise this, you can give the analogy of an instance of tug of war. Suppose there are two teams and they are equally strong.

Not all acids and bases are dangerous though. Many of the foods we eat and enjoy are acidic or basic. Lemon juice is quite a strong acid and baking soda is a base! How acidic or basic a substance is can be measured on the pH scale. This is an inverse logarithmic scale from 1-14. A strong acid is a 1, 7 is neutral (a substance which is neither ... Some acids and bases are also strong electrolytes. For example, a small amount of hydrochloric acid in the water allows the light to light up very brightly. So the acid is also a strong electrolyte and is called a strong acid. Acetic acid, on the other hand, dissolves but allows very little electricity to go through the water.

A pH of 7 means the solution is neutral (neither acid nor base, or both, depending on your point of view. Pure water is neutral, with a pH=7. The lower the pH, the stronger the acid and the higher the pH the stronger the base. pH numbers close to 7 are weak acids or bases respectively. Chapter 5 Acids, Bases, and Acid-Base Reactions. Figure 5.3. Acetic . Acid. Pure . acetic acid freezes at 17 ° C (63 °F). Therefore, it is a liquid at normal room temperature, but if you put it outside on a cold day, it will freeze. The solid has layered crystals that look like tiny glaciers, so pure acetic acid is called glacial acetic acid.

1. Strong Acid with a Strong Base, e.g. HCl with NaOH:Before NaOH is added, the conductance is high due to the presence of highly mobile hydrogen ions. When the base is added, the conductance falls due to the replacement of hydrogen ions by the added cation as H+ions react with OH−ions to form undissociated water.
