Question

Q19) Solutions A.B.C.D has pH
6,9,12,7respectively. The increasing
order of H+ ions concentration is:
O A <B<C<D
O C<B< D< A
O B<C<D<A
O D< A<C<A​

Answer 1

Answer:

C , B ,D , A

Explanation:

D is more basic that is it contains OH ions

as we move from right to left of pH scale the concentration of H increases. 6 lies to left f pH scale . so above mentioned order is Right

Answer 2

Answer:

Correct answer is option(2) C<B<D<A

Explanation:

More is the pH, then, more is the basicity.

So, A has least pH hence it is more acidic and has more H+

And, C has most pH and has less H+
