Message: | The molecular weight of Tris was 121.14:0.1mol/l, and the solution was 12.114g/l. Tris solution can absorb carbon dioxide from the air, so the bottle should be tightly closed. When Tris HCl solutions with different concentrations and pH values are prepared, a certain pH value of 0.05mol/l solution can be prepared first, and then diluted to the required concentration.
