The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
WebJul 8, 2024 · Explanation: Nitrogen dioxide is represented as NO2. It is a brown coloured gas. It is oxide of a non metal atom. In general the oxides of non metallic atoms are acidic. Hence oxide of nitrogen is also acidic. So the pH value of nitrogen dioxide is less than 7. WebMay 8, 2024 · By definition, a strong acid yields 100% of H 3 O + and A − when the acid ionizes in water. Table 2.4. 1 lists several strong acids. Table 2.4. 1: Some of the common strong acids and bases are listed here. For a strong acid, [ H +] = [ A −] = concentration of acid if the concentration is much higher than 1 × 10 − 7 M.
