Here are the essential concepts you must grasp in order to answer the question correctly.
Strong Bases
Strong bases are substances that completely dissociate in water to produce hydroxide ions (OH-). Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). While many strong bases are hydroxides, not all strong bases are exclusively defined as salts of the hydroxide ion, as some can be derived from other compounds.

pH Scale
The pH scale measures the acidity or basicity of a solution, with values ranging from 0 to 14. A pH of 7 is neutral, while values above 7 indicate basic solutions. The addition of a strong base to water typically results in a solution with a pH greater than 7, reflecting the increased concentration of hydroxide ions.

Solubility and Strong Bases
Solubility refers to the ability of a substance to dissolve in a solvent, such as water. While strong bases are characterized by their complete dissociation in solution, some compounds, like magnesium hydroxide (Mg(OH)2), are not very soluble. This does not disqualify them from being classified as strong bases; rather, it indicates that their strength is not solely dependent on solubility.
