Strong acids and strong alkalis both tend to be very corrosive and potentially lethal if you are exposed to them. The conductivity and the strength increases with $\ce{pH}$, but conductivity can be obviously affected by presence of salts.There is not a strict threshold between strong or weak alkaline $\ce{pH}$.It is often considered relatively and/or it depends on context. The word alkaline describes a water-based solution with a pH above 7.0. Is Ammonia a Strong Alkali?

Ask your question. So you should only think of the them as strong in the sense of strong means pKb near or less than zero. Litmus. NH4+ is called an ammonium ion. Superbases are stronger than hydroxide ions and cannot be kept in water; they provide examples of bases that do not contain a hydroxide ion (and are therefore strong Lewis and/or Bronsted-Lowry bases, but not Arrhenius bases). Indigestion tablets (antacids), Toothpaste, Cream cleaner, Bleach, Metal polish, Oven cleaner, Baking powder, etc. These substances all have different pHs.
