英文的化学题目~~~高手!
here are some measurements of solutions that were made using a pH meter.
A.8 B.9 C.6 D.3 E.7 F.10
(1)a bottle of soda powder solution has a pH of10. how do you think the pH would change when it is heated in the sunlight for several hour? why?
(2)if we put D and F together in a test tube, what would happen?
(3)list three chemicals whose pH are 7

Answer 1

翻译：以下是用PH计测出的一些结果
A.8 B.9 C.6 D.3 E.7 F.10
(1)一瓶PH值等于10的苏打水,为什么把它放在阳光下晒几个小时能使他的PH值发生改变呢?
加热后,或太阳暴晒一段时间后,水分蒸发并且温度升高,使氢离子浓度变化,PH值也发生变化
（2）如果我们把D和F倒在试管里混合,会有什么现象发生?
PH值会向6和10之间靠拢
（3）列出3种PH值等于7的化学试剂
常温下：蒸馏水,氯化钠溶液,硝酸钠溶液
