So let's look at this reaction again. So we know that HCL, when mixed in water, dissociates into a Hydride ion and a chloride ion. So now we have a solution that contains a bunch of H plus ions flowing around next to water. So what actually happens is a base pair or a pair of electrons down on the water grabs the H ion, producing hydronium ion. So actually, the Hydride ion produced by an Iranius acid is always associated with a hydronium molecule. And that's because our solvent is always water.
