Here's why:
* Acids have a pH less than 7 and release hydrogen ions (H+) in solution.
* Alkalis (also known as bases) have a pH greater than 7 and release hydroxide ions (OH-) in solution.
When an acid and an alkali react, the hydrogen ions from the acid combine with the hydroxide ions from the alkali to form water (H2O). This reaction also produces a salt, which is a compound formed from the remaining ions.
Here's a simplified representation:
Acid (H+) + Alkali (OH-) → Water (H2O) + Salt
Example:
* Hydrochloric acid (HCl) (acid) reacts with sodium hydroxide (NaOH) (alkali) to produce water (H2O) and sodium chloride (NaCl) (salt):
HCl + NaOH → H2O + NaCl
The neutralization reaction effectively cancels out the acidic and alkaline properties, resulting in a solution with a pH closer to neutral (7).
