You can think of the compound as being 100% … WebWhy is HCl a strong acid class 10? HCl is a strong acid because it has more number of hydrogen ions whereas acetic acid contains less number of hydrogen ions so its a weak acid , it can be varied by changing number of hydrogen ions in them .. What makes a strong acid? Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than …
WebWeak bases only partially dissociate in a solution, while the strong bases dissociate fully in a solution. Weak bases have pH 7.3 – 10, strong ones have pH 10 – 14. The weak bases have a lower equilibrium constant, while the strong bases have a higher equilibrium constant. Strong bases are highly reactive, while weak bases are less reactive.
