1·Carbon dioxide is like nitrogen in many ways, but if it is mixed with limewater, it causes the clear liquid to because milky, while nitrogen dose not. This is the test for carbon dioxide.
二氧化碳在许多方面类似于氮气，但如果它与石灰水混合，它就使清澈的液体变成乳状液，而氮气不能，由此可以鉴别热氧化碳。
2·When we pass an excess of carbon dioxide into the limewater, the white precipitate disappears. This is because the precipitate dissolves to form soluble calcium hydrogencarbonate.
我们把过量的二氧化碳通入石灰水时，白色沉淀物会消失，因为沉淀物反应生成可溶于水的碳酸氢钙。
3·Steaming liquid egg with limewater is a delicious dish with unique flavor.
石灰水蒸蛋是一道风味独特的特色佳肴。
4·The limewater treatment improved cane quality more quickly than the KH2PO4 treatment, but a longer duration of the effect was found in the later treatment.
石灰水处理甘蔗品质提高较快，而KH2PO4处理甘蔗品质提高效应维持时间相对较长。
5·In order to reduce the operation cost, a small dynamic test was done with the simulation of the operation conditions of the aeration basin, and calcined soda is being replaced by limewater.
为了降低运行成本，采用小型动态实验，模拟曝气池的运行条件，将石灰水代替纯碱以中和水质。
