Describe extraction of sodium from common salt.how and under what conditions sodium reacts with water ,hydrogen,oxygen,chlorine and nitrogen
Answers
Answer:
Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide.
Answer:
hey mate your answer is here
Explanation:
The procedure is called the Down's Process. Heat a mixture of Sodium Chloride and Calcium Chloride (the mixture is to lower the melting point of the salts and prevent the sodium metal from becoming gaseous) to about 600 degrees C in a closed container. Inside the container are two highly-charged electrodes. As the salt mixture melts, a misture of sodium and calcium is deposited on the cathode, and chlorine on the anode. Be warned, you have now created pure forms of two EXTREMELY dangerous chemicals at very high temperatures. Not recommended outside of a heavily industrialized setting with stringent safety controls.
