Are you suggesting that the pH of the acid is 2?

You have diluted the acid 10 fold. The H+ conc has dropped 10 fold. What will that do to the pH...remember pH is a logarithmic scale..

Thanks but I was simply trying to nudge the OP towards the correct answer aha. Without sounding self indulgent, I already knew the answer :biggrin:
