What is the Difference Between Alkali and Base?
🆚 Go to Comparative Table 🆚The main difference between an alkali and a base lies in their solubility in water. An alkali is a base that dissolves in water, while not all bases dissolve in water. Here are some key differences between alkalis and bases:
- Solubility: Alkalis dissolve in water, while some bases do not.
- Examples: Examples of bases that are not alkalis include zinc hydroxide (ZnO) and copper oxide (CuO). Examples of alkalis include potassium hydroxide (KOH) and sodium hydroxide (NaOH).
- Neutralization: Both alkalis and bases neutralize acids, but they do so through different processes. Bases release hydroxide ions (OH-) and accept protons, while alkalis release OH- ions and accept a proton.
In summary, all alkalis are bases, but not all bases are alkalis. Alkalis are water-soluble bases, while some bases are not soluble in water. Both alkalis and bases neutralize acids, but they do so through different processes.
Comparative Table: Alkali vs Base
The main difference between an alkali and a base is that an alkali is a base that dissolves in water, while not all bases dissolve in water. Here is a table summarizing the differences between alkalis and bases:
Property | Base | Alkali |
---|---|---|
Definition | A base is a substance that can neutralize acid by reacting with hydrogen ions. | An alkali is a base that dissolves in water. |
Solubility | Bases do not necessarily dissolve in water. | Alkalis dissolve in water. |
Examples | Zinc hydroxide (ZnO), copper oxide (CuO). | Potassium hydroxide (KOH), sodium hydroxide (NaOH). |
In summary, all alkalis are bases, but not all bases are alkalis. Bases can neutralize acids and release OH− ions, while alkalis are water-soluble bases that release OH− ions when dissolved in water.
