	You would have to add it very slowly, because what you actually
want in solution is the bicarbonate.  This will be formed as the CO3--
reacts with the CO2 in the water, but if you add a lot all at once, you
will effectively wipe out the CO2 and the pH will take a big jump.  It
would not be difficult to hit pH 10.  Be _very_ cautious.
