WebApr 5, 2024 · Weak bases and weak acids are considered weak electrolytes. Strong bases, strong acids, and salts are considered strong electrolytes. ... Ostwald’s dilution law is applicable. Ostwald’s dilution law cannot be applicable. Since it is ionised partially in the molten state or solution it contains ions and undissociated molecules. WebSimilarly if the indicator is a weak base, its ionisation is large in acids and low in alkalies due to common O H − ions. Considering two important indicators, Phenolphthalein (a weak acid) and Methyl orange (a weak base). Ostwald theory can be illustrated as follows: Phenolphtalein : It can be represented as HPh. It ionises in solution to a ...
