Answer 1

Answer:

solu. A has more H+ ions

solu. A is acidic

solu. B is basic

remember to mark me brainliest :)

Answer 2

Answer: A has more hydrogen concentration.

B is basic and A is acidic

Explanation: ph= -log (h+)

So by this H+ concentration is -ve

Lesser the concentration more the ph

So by this A has more h+ concentration

And in ph scale the solution having ph value below 7 is acidic, having 7 as ph is neutral, having more than 7 as ph is basic
