| 然后，取反应之后的母液10毫升，滴加硝酸银溶液，有明显的黄色沉淀产生，在继续滴加氨水，可观察到沉淀有所减少但没有消失。所以可预测最后的沉淀物中含有碘化银。过滤沉淀，在避光条件下干燥，然后用PXRD 和 XPS 对其进行检验。从PXRD 图中可以看出，沉淀物的出峰位置与纯的碘化银的出峰位置基本重合。此外，从XPS的测试结果中可以得出，此沉淀物的确是含有碘化银。预测正确。 |

| Then, an amount of 10 ml of reacted stock solution was taken and added with a few droplets of silver nitrate solution, it is apparent that yellow colour precipitate is form and a decrease in yellow precipitate can farther be observed after addition of ammonia into the mixture. The final precipitate obtained therefore can be predicted consists of silver iodide. The precipitate was then subjected to PXRD and XPS testing after filtration followed by drying process without sunlight. From the PXRD diffratogram, the peak position of the precipitate was basically overlap with peak position of pure silver nitrate. Furthermore, the composition of silver nitrate in the precipitate was detected and determined by the XPS testing. The prediction is corret. |

| Then an amount of 10 ml of reacted stock solution was taken and added with a few droplets of silver nitrate solution, and it can be clearly seen that yellow precipitates formed and with the subsequent addition of ammonia into the mixture the amount of precipitates decreased but did not disappear. It then can be predicted that there is silver iodide in the final precipitates. The precipitates were then subjected to PXRD and XPS testing after filtration followed by light-resistant drying process. It can be seen from the PXRD pattern that the peak position of the precipitate and that of pure silver basically overlap. Moreover, the XPS testing also confirmed the presence of silver nitrate in the precipitates. So the prediction is correct. |
