Explain why methanol and sodium carbonate were both able to dissolve in water, but only sodium carbonate was able to conduct electricity in solution. Cerium is a chemical element with the symbol Ce and atomic number 58. Methanol will be partly soluble in water due to its small size and the presence of the OH group in the molecule and its very polar nature. Its chemistry is well explored. Sodium Carbonate will be very soluble in water because of the positive ions of sodium attached to the negative ions of the carbonate. This is especially important if you are making food, since an impure product may contain dangerous contaminants. Generally, elemental sodium is more reactive than lithium, and it reacts with water to form a strong base, sodium hydroxide (NaOH). The methanol is in residence with the sodium carbonate containing solution for between 10 and 100 minutes. The alcohol-containing solution (16) has an alcohol concentration ranging between 50 % and 100 %. The difference between the two molecules is that methanol has a hydrogen atom single-bonded to its oxygen, which directly results in a single bond between the carbon and oxygen atoms (C-OH), instead of the double bond that is present between the carbon and oxygen atoms in an aldehyde (H-C=O). 3.11 g/100 mL (25 C) methanol Insoluble in alcohol, acetone.
