pH of two solutions A and B are 2 and 5 respectively. This means that :
(A) Solution A is 3 times more basic than B
(B) Solution A is 3 times less basic than B
(C) Solution A is 1000 times more basic than B
(D) Solution A is 1000 times less basic than B

Dear student,
From the formula,pH=-logH+Given pH of solutions A, B as 2 and 5 respectively then,based on above formulawe getH+  for solution A =102Where as for Solution B isH+ =105Hence this shows that Solution Ais 103 or 1000 times less basic than Solution B

Option 'D' is correct
