What can strong alkali dissolve?

Answer 1

Alkalis, and similarly, acids, cannot "dissolve" anything beyond the capacity of the water which partially comprises them. However, under the assumption that this question instead refers to "with what a strong alkali might react," a simple answer would be; anything at all acidic. The extent of reaction will vary with the strength of the acid, but any acid should react at least partially, oweing to its chemical nature. As explained at GCSE or o-level chemistry, acids and alkalis react due to the following: Acid = KkH Alkali = KfOH where Kf and Kk represent respectively positively and negatively charged molecules. Consequently, Acid + Alkali -> Metal salt + Water ie. KkH + KfOH -> KkKf + H2O

Answer 2

Strong alkalis can dissolve substances like grease, oils, fats, protein-based materials, and some minerals. However, they may not dissolve certain materials like plastics, rubber, and some metals. It is important to handle strong alkalis with care due to their corrosive properties.
