[14] Because of the high solubility of its compounds, sodium salts are usually isolated as solids by evaporation or by precipitation with an organic antisolvent, such as ethanol; for example, only 0.35g/L of sodium chloride will dissolve in ethanol. Therefore electrons will be added. The reaction is most vigorous with methanol and decreases with increasing molecular weight of the alcohol. [97] Excess sodium in the soil can limit the uptake of water by decreasing the water potential, which may result in plant wilting; excess concentrations in the cytoplasm can lead to enzyme inhibition, which in turn causes necrosis and chlorosis. Sodium is more reactive than lithium because sodium is larger in size. In a comparatively dry atmosphere, sodium burns quietly, giving off a dense white caustic smoke, which can cause choking and coughing. This means that Na has a greater atomic radius than Li. Instead of maintaining the same structure while varying in composition, the material underwent a structural transformation. This means that Na has a greater atomic radius than Li. This reaction is used in the preparation of several of the transition metals themselves, including titanium and tantalum. [85] Studies have found that lowering sodium intake by 2g per day tends to lower systolic blood pressure by about two to four mmHg. [19], Like all the alkali metals, sodium reacts exothermically with water.
