WebbWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +. Webb12 aug. 2024 · The solubility of ph3 in water is very low. In fact, it is so low that it is not detectable by most methods. The only way to measure the solubility of ph3 in water is to use a very sensitive method, such as nuclear magnetic resonance spectroscopy. ph3 is soluble in water because it is a polar molecule. ph3 has a large dipole moment because …
