Answer:
A rule of thumb is that 1.5 lbs. of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm. If your pool's pH is tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
Answer:
26.7 mL
Explanation:
M1*V1 = M2*V2
M1 = 12M
V1=?
M2 = 2.5M
V2=128 mL
12M*V1 = 2.5M*128 mL
V1 = 2.5*128/12 mL≈ 26.7 mL
