And that means it increases the concentration of our oh ions found in water. Therefore, this guide by the submission must be an Iranius base. Now, Arrangeous Aspen bases are always found in water that's by definition, whenever we talk about our radius acid bases, we talk about solutions in which our solvent is water. 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.
