WebAnswer (1 of 5): H2CO3—Carbonic acid is weaker as it ionises partially to produce lesser hydrogen ions per mole of the acid in aqueous solution. The strength of an acid refers to its ability or tendency to lose a proton, or an H⁺ ion. A strong acid is one that completely ionises in solution stat... WebJan 5, 2024 · Consider simply aqueous solutions of $\ce{H2S}$ and $\ce{HCl}$.It is pretty much known that $\ce{HCl}$ is stronger than $\ce{H2S}$ in water. The reason behind that first is the electronegativity of $\ce{Cl}$ is higher than $\ce{S}$, so, in a polar medium, it becomes easier for the $\ce{H-Cl}$ bond to break than the other one.
