The biggest difference from all the previous compounds is that sodium hydroxide is very corrosive, which is why it was given the name caustic soda. This compound is soluble in water, ethanol and methanol. Sodium hydroxide is manufactured using the chloralkali process which is an industrial process. The sodium chloride is then electrolyzed and sodium hydroxide is produced in the cathode. A cathode is a type of electrode where electrons move. The water is then condensed from the hydrogen gas and the hydroxide ion. The hydrogen is then removed from the equation so that the hydroxide bonds with the sodium. Sodium carbonate, also known as washing soda, is a white solid and has the chemical formula Na2CO3. The molar mass of sodium carbonate is 105.9888 g/mol. Sodium carbonate forms naturally; When sodium is released from igneous rocks and when it is carried by rivers it comes into contact with carbon dioxide, it is in the form of sodium carbonate. Just to get sodium carbonate to its boiling point, it's impressive, you have to bring it to a temperature of 1,554° F and its melting point is 2,912̊
