PH值的英文全称：potential of hydrogen potential of hydrogen的中文意思：酸碱度 pH，亦称pH值、氢离子浓度指数、酸碱值、[离𢀖]（音ㄌㄧㄥˊ）标值，是溶液中氢离子活度的一种标度，也就是通常意义上溶液酸碱程度的衡量标准。这个概念是1909年由丹麦生物化学家瑟伦·索伦森提出的。“pH”中...

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...
