反应试验：取100ml样品倒入150ml分液漏斗中，加入10ml新煮沸并冷却的蒸馏水，振荡混合2min，然后静置分层，将下层溶液放入试管中，先加入酚酞指示剂1滴，如不显红色，再加甲基橙指示剂1滴，也不显红色，则为中性。 Acidity-basicity Test(这个“反应试验”实在不知道怎么译好，由于这实际上是一个酸碱度测试所以就这样译了，不知妥不妥？) Transfer 100ml of the sample of be examined into a 150-mL separatory funnel, add 10ml of boiled and cooled water. Mix by rocking for 2min, and allow the funnel to stand until there is a sharp demarcation line between the two layers. Transfer the water layer into a test-tube, add 1 drop phenolphthalein indicator, the solution is not pink. Further add a drop methyl orange indicator, the solution is also not pink.
