WebAn acid is a substance or compound that releases hydrogen ions (H +) when in solution. In a strong acid, such as hydrochloric acid (HCl), all hydrogen ions (H + ), and chloride ions (Cl - ) dissociate (separate) when placed in water and these ions are no longer held together by ionic bonding. Web11 feb. 2024 · The pH scale – ranging from 0 – 14 actually indicates the concentration of hydrogen ions. 0 is highly acidic. As the numbers increase the acidity decreases finally reaching 7 which is neutral. From 8 to 14 alkaline values are determined. Lesser hydrogen ions will give you an increased number in the pH scale and more ions will decrease the ...
