Answer 1

s < p< r< q , this is the answer hope it helps ☺️

Answer 2

Answer:

Decreasing order : Q>R>P>S

3>5>7>11

Explanation:

since ph value is inversely proportional to concentration of H+ ions. i.e if the ph value is more than conc. of H+ ions would be less and visa versa. There fore solution Q ( ph value is 3) will have highest conc. of H+ ions as compared to other solutions given above, followed by R ( ph value is 5),then P(ph value 7, which is actually a neutral solution) at last S (ph value 11) would have the least conc. of H+ ions since the ph value is highest in the given solutions...
