你觉得呢？如果将红甘蓝加入沸水中，就会制得一种特殊的蓝色溶液。硫酸是一种常见的酸，它会使溶液变红。氨是一种常见的碱，它会使溶液变成绿色。·你知道酸和碱的其他性质吗？·如何区分酸和碱？在您的活动化学日志中记录您对这些问题的想法。准备好与你的小组和班级讨论你的回答。
What Do You Think? If you add red cabbage to boiling water a special bluish colored solution is made. Vinegar, a common acid, will turn the solution red. Ammonia, a common base, will turn the solution green. • What are some other properties of acids and bases you know about? • How can you tell the difference between an acid and a base? Record your ideas about these questions in your Active Chemistry log. Be prepared to discuss your responses with your group and the class.
