sorry, the question got cut off, here it is again:
6. The proper pH range for a swimming pool is between 7.2 and 7.8. Most pools use two substances, NaCO3 and HCl, to maintain this range. How would you adjust the pH if you found it was 8.2? What would you do if it was 6.9?

if it was low, add some sodium carbonate. if it was high, add some HCl.
I think actually they use HOCl and HCl (available chlorine). You get this when you bubble Cl2 in water.

NaCO3H and H2CO3
the first is a salt, the second is an acid and the pH is given
by pH= pKa+ log ([NaCO3/H2CO3)
with the pKa=7.4
It is a buffer system existing in the blood and you can use it to adjust the pH in that limit
I am sur that your answer has mistake in the formula

where is the question?
Na2CO3 is used to increase the basisity of the water since its a weak base
