摘　　要：通过实验观察到铝和碳酸钠溶液可以反应并冒出气泡,为此,设计了几组对比实验并进行了理论分析。发现常温下,铝与浓度在6.5×10^-6 mol/L以上的碳酸钠溶液(pH≥8.8)是可以反应的,而且生成四羟基合铝酸钠、碳酸氢钠和氢气。Through experiments, it was observed that aluminum and sodium carbonate solutions could react and bubbled out. Therefore, this paper designed several groups of comparative experiments and analyzed theoretically. At room temperature, it was found that aluminum could react with sodium carbonate solution(pH≥8.8) with the concentration of more than 6.5×10^-6 mol/L, and generated four hydroxy aluminum acid sodium, sodium bicarbonate and hydrogen.
