You can also do double hydrolysis experiments, such as the mixing of NaHCO3 and Al2(SO4)3 solution, which immediately produces a large number of bubbles and precipitates, which are used for fire fighting and extinguisher principle;
It can also be used as a flame reaction to detect the presence of Na+.
It can also be used in stability experiments, such as NaHCO3 heating decomposition experiment;
