How much sodium bicarbonate should be added to a 2,000 gallon spa to increase the total alkalinity by 14 ppm?

6.27 oz
7.50 oz
8.00 oz
10.00 oz

The correct answer is: 6.27 oz

Adding any amount greater than 6.27 oz of sodium bicarbonate to a 2,000 gallon spa will result in an increase in alkalinity greater than 14 ppm. Option B and C are both higher than the correct answer and will result in an increase greater than 14 ppm. Option D is significantly higher than the correct answer and may result in an undesirable increase in alkalinity. Therefore, option A is the most accurate and precise amount of sodium bicarbonate to add to achieve an increase in total alkalinity of 14 ppm.
