Answer:
The H+ concentration is 
Explanation:
We know that for any solution,
pOH + pH = 14
Given,
pOH = 9.70,
Therefore using formula,we get,
pH = 14 - pOH,
pH = 14 - 9.70;
pH = 4.30
We also know,
If Concentration of H+ in a solution in C,
Then,
pH = -log(C) ------(Formula 1) and C = 
----(Formula 2)
Therefore,
using formula 2, we get,
C =
C = 
M.
Therefore concentration of H+ in the given solution is
A substance in the air which can change the surface of limestone would be oxygen, O2.
