碳族元素是高中化学各类考试试题当中极为常见的元素,也是各类化合物的有效组成部分.在近些年的高考试题当中,巳波及到新型无机非金属材料等相关内容.案例1在某一实验当中,选用某二价金属碳酸盐和碳酸氢盐的混合物跟足量的盐酸发生反应,在此过程中消耗的H+和排放的CO2的物质的量比是6∶5,试求此类混合物中碳酸盐和碳酸氢盐的物质的量比是多少().A.1∶4 B.1∶3 C.1∶2 D.1∶1
Carbon group element is a very common element in all kinds of high school chemistry exams and is also an effective component of various kinds of compounds. In recent years, the college entrance examination examinations have spread to new inorganic nonmetallic materials and other related content. In an experiment, a mixture of a divalent metal carbonate and bicarbonate was used to react with sufficient amount of hydrochloric acid, the amount ratio of H + to the amount of carbon dioxide emitted during the process was 6: 5. The ratio of carbonate to bicarbonate species in the mixture is () .A.1: 4 B.1: 3 C.1: 2 D.1: 1
