2.12 explain, in terms of dissociation, why hydrogen chloride is acidic in water but not in methylbenzene

Hydrogen chloride is acidic in water because the molecules ionise when dissolved in water. We can prove this because the effect on blue litmus paper is that it turns red. 

 However hydrogen chloride in methylbenzene does not ionise and therefore is not acidic. 

 A solution of hydrogen chloride in water is called hydrochloric acid.

    Is this double or triple award?

      Don't know if it's also on the double award checklist, but it's definitely on the triple award one

    Isn't just simply the extension of dissociation???

    If it’s not acidic, is it alkaline or neutral?
