Name a weak and strong alkali

A weak alkali is Ammonium Hydroxide (NH4OH) and a strong alkali is Sodium Hydroxide (NaOH).

Here's a step by step explanation:

1. Alkalis are substances that react with acids and neutralize them. They are usually metal hydroxides and they are found in various household products.

2. A weak alkali does not fully ionize in a solution, meaning it does not release all of its hydroxide ions (OH-) when in a solution. An example of a weak alkali is Ammonium Hydroxide (NH4OH).

3. On the other hand, a strong alkali fully ionizes in a solution, releasing all of its hydroxide ions. Sodium Hydroxide (NaOH) is an example of a strong alkali. It is used in various industrial processes and is also found in some household cleaning products.
