A 100 cm3 of 2 mol dm-3 hydrochloric acid was poured into a polystyrene cup. 8 grams of anhydrous sodium carbonate was added with. Initial temperature was 20.0 C and final temperature was 25.0 C. The balanced equation I got was 2HCl (aq) + Na2CO3(aq) → 2NaCl (aq) + CO2(g) + ...
Under the optimum reaction conditions (molar ratio of methanol to α-naphthylacetic acid 25, mass ratio of HC1 to α-naphthylacetic acid 17%, reaction time 2h) the yield was 97.4%.Zhaohui WangShan JiangXiaoxuan Xie合成化學編輯部合成化學
Hydrochloric acid (HCl) is a common acid used in the laboratory to make acidic solutions. Aqueous HCl solutions show low pH values because HCl is a strong acidic compound. You can easily check this by using a pH meter. In theoretically, pH value can be found by substituting concentration ...
