The pKa of hypochlorous acid is 7.530. A 53.0 mL solution of 0.100 M sodium hypochlorite (NaOCl) is titrated with 0.303 M HCl. Calculate the pH of the solutiona) after the addition of 6.47 mL of 0.303 M HCl. b) after the addition of 18.4 mL of 0.303 M HCl. c) at the equivalence point with 0.303 M HCl.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
