Help!just a little Chemical question...
When working in the laboratory,you discover that the solutions you are working with are tomato with a pH of 4 and soap with a pH of 10.By comparing the pH of these substances with that of pure water,would you find that these substances are acidic or basic?Explain.Thx
thx
西红柿的PH是4,肥皂的PH是10,水则是中性的,拿PH试纸,分别测试,西红柿的偏红,是酸性,肥皂的偏蓝是碱性,而水的基本不变,是中性!
= =# 纯水 pure water pH=6.5--8.0 去离子水的pH不太好测
tomato 番茄 pH=4 偏酸 acidic
肥皂 soap pH=10 偏碱 basic
应该是这样的吧…………………………
