1.52 understand that electrolysis involves the formation of new substances when ionic compounds conduct electricity

In electrolysis ionic compounds conduct electricity. Positively charged ions move to one end, negatively to the other, these are then turned into atoms (by losing their charge) and so new substances are formed.

    1. excuse me!
      this is an educational website that helps people in sciences (chemistry).
      and you should not use offensive language towards people who visit websites who need help in education,
      so please apologize before you become identified as an absolute disrespectful disgrace to humanity.

  2. When you go through their whole blog and shout hate towards them, that they spent time on. A better way to do this would either to leave constructive criticism or even answer the question yourself.

  3. Hiya,
    Just need to clarify, so the charged ions balance out (positive = negative) so it becomes neutral; and becomes an atom?

    1. At the cathode/anode they either gain electrons or lose electrons to become neutral
      e.g. potassium gains an electron
      K+ + e- ===> K
      or Bromide loses an electron to become bromine
      2Br- ===> Br2 + 2e-
