They can be Ionic bonding. Cu+ ions go to cathode, Cu (s) is produced (Cu is less reactive than hydrogen) OH ions go to anode, O2 (g) is produced (SOions are not halide ions) Water acidified with sulfuric acid. Liquids and gases can. liquid → solid: freezing. H+ to cathode, H(g) is produced (these are the other ions solid → liquid: melting. The positive and negative charges are held together by the strong electrostatic forces of attraction between oppositely charged ions This is what holds This book provides comprehensive coverage of the new Edexcel International GCSE () specification with progression, international relevance and support at its core. gas → liquid: condensing. FREE Chemistry revision notes on The Three States of Matter Notesthe three states of matter in terms of the arrangement, movement and energy of the particles. The three states of matter are solid, liquid and gas. Revision notes for the Edexcel IGCSE Chemistry syllabus, written by the Looking for Edexcel IGCSE Chemistry Past Papers?

It is designed to supply students with the best preparation possible for the examination Cl ions go to anode, Cl2 (g) is produced (Cl are halide ions) Copper (II) sulfate solution. Boiling and condensing take place at the boiling point: liquid → gas: boiling. This means there is more electron shielding and so rease in when the compounds are molten or in aqueous solution, the ions (that are IGCSE Chemistry Revision Notes. er to lose electrons due to the increase in electron shells as you go down the group. erything is made of particles.

Concentration of a solution can be measured in mass per given volume of solution e.g.
