Answer:
Given:
The pH of solution A = 2.4
The pH of solution B = 9.4.
Solution:
The hydrogen ion concentration is the amount of hydrogen ions present in the given solution usually expressed in terms of moles pere litre .
(A) hydrogen-ion concentrations of the solution.
Now,
The hydrogen ion concentration of the solution A
Similarly
hydrogen ion concentration of the solution B
(b) The hydrogen ion concentration of solution A 
is and the solution B is 
so we can conclude that the hydrogen ion concentration of solution A is 
times greater than solution B
(c) The solutions A and Solution B differ by 7 order of magnitude
Answer:
