Do stronger bases have higher ph
WebExercises. 1. a) Draw the Lewis structure of nitric acid, HNO 3. b) Nitric acid is a strong acid – it has a pK a of -1.4. Make a structural argument to account for its strength. Your answer should involve the structure of nitrate, the conjugate base of nitric acid. Show Solution. WebNov 29, 2024 · As a result, strong bases commonly have pH values of around 13 or 14. For example – Lithium hydroxide, Sodium hydroxide, Potassium hydroxide, Rubidium hydroxide, Cesium hydroxide, etc. The chemicals that do not completely dissociate are known as weak bases ( have a pH value in the range of 7 – 10).
