electryolosis of sodium chloride solution and the other one

Question 1

how can concentrated sodium chloride solution be separated by?

Answer 1

electryolosis

Question 2

where is hydrogen made?

Answer 2

at the negative cathode

Question 3

where is chlorine made?

Answer 3

at the posotive anode

Question 4

where does sodium hydroxide form?

Answer 4

in solution

Question 5

why is it important to use inert electrodes?

Answer 5

so that the products don’t react before they are collected and the electrodes do not dissolve. Hydrogen and chlorine are very reactive

Question 6

what happens during the electrolysis of NACL solution?

Answer 6

Na+ ions go to negative
CL- and OH- go to posotive
cathode, hydrogen is made- electron are gained so its reduction

Question 7

what is the equation at the cathode?

Answer 7

2H+ + 2e- —- H2

Question 8

what happens at the anode, equation?

Answer 8

2CL- - 2E- — CL2

Question 9

what do the non discharged ions make?

Answer 9

sodium hydroxide solution

Question 10

what is the equation for this?

Answer 10

NA+ + OH- — NAOH
