Question

Classify the following into strong bases and weak bases:

$\mathrm{Mg}{\left(\mathrm{OH}\right)}_2,\mathrm{NaOH},\mathrm{Ca}{\left(\mathrm{OH}\right)}_2,{\mathrm{NH}}_4\mathrm{OH},\mathrm{KOH}$

Answer 1

1. Strong bases are the bases that completely ionize in their solution.
2. Weak bases are the bases that partially ionize in their aqueous form.
3. From the given compounds, Magnesium hydroxide$\mathrm{Mg}{\left(\mathrm{OH}\right)}_2$ sodium hydroxide$\left(\mathrm{NaOH}\right)$, and potassium hydroxide$\left(\mathrm{KOH}\right)$ are strong bases because they fully ionize in their solution.
4. Calcium hydroxide $\left(\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\right)$ and ammonium hydroxide $\left({\mathrm{NH}}_4\mathrm{OH}\right)$ are weak bases as they partially ionize in their solution.
