Which chemical would be most appropriate to adjust the pH in the pool to an acceptable level?

Calcium Chloride
Sodium Bicarbonate
Sodium Carbonate
Sodium Hypochlorite

The correct answer is: Sodium Carbonate

Sodium Carbonate would be the most appropriate option to adjust the pH in the pool to an acceptable level. Calcium Chloride, while it can be used to adjust pH levels, is more commonly used for increasing the hardness of pool water. Sodium Bicarbonate can also be used to raise the pH, but it is not the most effective option for this purpose. Sodium Hypochlorite, commonly known as bleach, is used to disinfect and chlorinate pool water, not adjust pH levels. Therefore, Sodium Carbonate would be the best choice for adjusting the pH in the pool.
