| Classical means of separation were based on the small differences in basicity and solubility. |
| Urea and substituted ureas exhibit a weak basicity and may bind a superacid in the form of a quarternary ammonium salt. |
| When some sodium chloride solution is then added to one of the two portions, the basicity of the solution is distinctly increased. |
| The K86R substitution results in the change in the basicity of the residue. |
| Apart from the concentrations of salts, basicity and silica from the purging itself, descalers are used for the cleaning of circuits. |
| Usually, a basicity above 3.5 provides good absorption and holding capacity for calcium phosphates and calcium sulfides. |
