Account for the following : (i) State the relation between hydrogen ion concentration of an aqueous solution … ) How do [H+] ions…

Answers:

(I) If H+ ion concentration is more, pH will be less and vice versa or pH of a solution is inversely proportional to H* ion concentration (pH = – log [H+]

(ii) This solution is neutral. 

(iii) 1 M NaOH solution (basic solution). 

(iv) When the pH in the mouth is below 5.5, bacteria present in the mouth produce acids by degradation of sugar and corrode the tooth enamel. It can be prevented by using tooth pastes which are generally basic.

 (v) [H+] ion exist in water as hydronium [H3O]* ion.
