WebWhat does it mean to say that ions are hydrated when an ionic substance dissolves in water? Water: Water contains hydrogen bonds and hence water is a polar molecule. … WebCopper (I) chemistry is limited by a reaction which occurs involving simple copper (I) ions in solution. This is a good example of disproportionation - a reaction in which something oxidises and reduces itself. Copper (I) ions in solution disproportionate to give copper (II) ions and a precipitate of copper. The reaction is: soho indonesia
