| 1 | Investigating the solubilization by Phase solubility method. | |
| 2 | Measure the solubility of a compound in aqueous solution. | |
| 3 | So to choose the high calcium and good solubility of calcium. | |
| 4 | Secondly, the hardness of water also affects the solubility of the active ingredient of tea. | |
| 5 | "More carbon dioxide can dissolve in cold water than warm, " he said. |
