从益阳回来之后,小明家的餐桌上添了几枚松花蛋。拨开蛋皮可见蛋面上的松花形态优美,堪与艺术品媲美。松花蛋面上的松花是怎样形成的呢?小明决定与化学兴趣小组的同学一起探个究竟。【查阅资料】松花蛋的制作工艺:一般是用水将灰料[主要成分是生石灰(CaO)、草木灰(含K_2CO_3)、纯碱(Na_2CO_3)、食盐(NaCl)等]调成糊状料泥,涂于新鲜鸭蛋表面,密封保存一段时间后,即可得到松 After coming back from Yiyang, Xiao Ming’s table added a few pieces of pine eggs. Picking open egg skin can be seen on the surface of pine flower beautiful shape, worthy of artwork comparable. Songhuahua surface of pine is how to form it? Xiao Ming decided to explore with students of chemistry interest group. [Access to information] Songhua egg production process: the general is the use of water to the gray material (the main components are lime (CaO), ash (including K_2CO_3), soda ash (Na_2CO_3), salt (NaCl) Fresh duck egg surface, sealed for a period of time, you can get loose
