制备碳酸钙溶液,为了增大其溶解度,加入一定量的碳酸钠。什么原理?A coppercarbonate solution was prepared by adding 6.1 part weight of cupric carbonate to 80.9 parts by weight water. The copper carbonate was rendered more soluble by the addition of 4.9 parts by weight sodium carbonate. 为什么呢?按照溶解平衡来说,CuCO3在水中离解为 铜离子 和碳酸根,当碳酸根增多的时候不是应该平衡向左移动,从而阻碍 碳酸铜 的溶解么?查看更多8个回答 . 17人已关注
