By reaction stoichiometry, 2 moles of hydrochloride acid react with 1 mol of calcium oxide, then 3.56 moles of acid require 1.78 moles of calcium oxide. The 1M acid was the most vigorous and a large amount of bubbles were observed during the reaction. (a) Write the net ionic equation of the reaction. As long as the soda is dry, no reaction occurs. Thioglycolic acid with a pKa of 3.83 is about 10 times stronger an acid than acetic acid (pKa 4.76): HSCH 2 CO 2 H → HSCH 2 CO 2 − + H + The second ionization has a pKa of 9.3: HSCH 2 CO 2 − → − SCH 2 CO 2 − + H + Thioglycolic acid is a reducing agent, especially at higher pH. Acid rain is due to dissolved non-metallic oxides (S O 2 , N O 2 , P 2 O 5 , e t c.) 10 mL of acid rain sample required 5 mL of 0.01 M C a (O H) 2 for making it neutral.
