How to Dilute Acid | Sciencing
By contrast, adding acid to water creates a small pool of dilute acid at the moment of contact. The reaction is still exothermic but releases little heat. The chance for bubbling and splashing is greatly reduced, and the dilute acid produced is less harmful than in the prior situation.
Acid - Wikipedia
Svante Arrhenius attributed the properties of acidity to hydrogen ions (H +) or protons in 1884. An Arrhenius acid is a substance that, when added to water, increases the concentration of H + ions in the water.  Note that chemists often write H + (aq) and refer to the hydrogen ion when describing acid-base reactions but the free hydrogen nucleus, a proton, does not exist alone in water
