【题目】The pH of a solution describes its acidity. Each one-unit decrease in the pHmeans that the solution is 10 times more acidic. For example, a pH of 4 is10 times more acidic than a pH of 5.Cola is 104 times more acidic than water. What is the pH value of cola? 相关知识点...
这里是主谓一致的问题,increase在这里是动词,修饰concentration,浓度,是个度量名词,不可数的,所以谓语动词用单数,加s,变成increases.前面的动词decline也是用的单数,修饰Ph.整句话的意思是:溶液的PH值随着氢原子浓度的增加而降低.相关推荐 1The PH of a solution declines as the concentration of hydrogen ions increa...
