In which year is concentration of hydrogen ion the highest?
(A) 2002
(B) 2008
(C) 2011
(D) 2005
Answer -
Now,
- Acids increase H+ concentration
- More acidic , more H+ concentration
- Thus, lesser ph , more H+ concentration
Hence, in 2002 the pH value of rain was lowest indicating highest concentration of hydrogen.
So, the correct answer is (a)
