If your baby is younger than 4 months, Health Canada recommends boiling the water for use in mixing formula for 2 minutes.
Problem #2: Another variation: Assume that you prepared a solution by adding 0.05 mL (1 drop) of 0.500 HCl to 5.00 x 10 7 mL of pure water. Calculate the resultant pH. (Hint: the answer is not pH = 9.3; add up the hydronium ions from ALL sources). Solution:The key is to remember that pure water is naturally 1.00 x 10Â¯ 7 M in hydrogen ion.ssume that you prepared a solution by adding 0.05 mL (1 drop) of 0.500 HCl to 5.00 x 10 7 mL of pure water.
