一、等质量的不同种活泼金属单质与足量的稀酸溶液反应时,放出气体的质量,可用反应生成的盐中金属元素的化合价与其原子量之比来衡量.其比值大者,放出气体的质量较大.
First, the quality of different kinds of active metal element and a sufficient amount of dilute acid solution, the release of gas quality, the reaction can be generated by the salt of the metal element of the valence and its atomic weight ratio to measure the ratio of the larger, the release of gas The quality is bigger.
