根据温度对化学平衡移动影响的原理：升高温度，平衡向吸热方向移动；降低温度，平衡向放热方向移动。我们设计了利用颜色变化来反映温度变化的实验：绿色的水合氯化镍(含乙醇)溶液受热转变为黄色的氯化镍溶液；受冷颜色随之逆转，由黄色的氯化镍溶液转变为绿色的水合氯化镍溶液。
根據溫度對化學平衡移動影響的原理：升高溫度，平衡嚮吸熱方嚮移動；降低溫度，平衡嚮放熱方嚮移動。我們設計瞭利用顏色變化來反映溫度變化的實驗：綠色的水閤氯化鎳(含乙醇)溶液受熱轉變為黃色的氯化鎳溶液；受冷顏色隨之逆轉，由黃色的氯化鎳溶液轉變為綠色的水閤氯化鎳溶液。

According to the theory of the effect of temperature on the chemical equilibrium, the chemical equilibrium shifted to the endothermic direction with the increase of the temperature. However, the exothermic direction was shifted with the decrease of the temperature. An experiment was designed to study the change of the temperature according to the color. The green hydrated nickel chloride ( including ethanol) solution was changed to the yellow nickel chloride when it was heated, however, an opposite result was proposed if it was cooled.
