WebAug 13, 2013 · "Soda lime is 85.0% NaOH and 15.0% CaO. What volume of 0.500M Hydrochloric Acid is required to completely neutralise 2.50g of the Soda Lime?" Hint: Consider the reactions separately Homework Equations Formation of Soda Lime: CO 2 + H 2 O >> H 2 CO 3 H 2 CO 3 + 2NaOH >> Na 2 CO 3 + heat Na 2 CO 3 + Ca(OH) 2 >> CaCO 3 + … WebLimestone chips (or agricultural lime, or 500-mg antacid tablets) HCl, about 0.25 M (may need to standardize—consult instructor) Standardized NaOH, about 0.1 M (from Experiment 18) ... We do that because the reaction of HCl with CaCO3 is not instantaneous, and as acid is consumed in the reaction, its concentration decreases, so the rate of ... WebNov 24, 2024 · As a result of the acid-carbonate reaction, carbon dioxide is produced and the lime water turns milky. In this reaction setup, lime water, a dilute calcium hydroxide (\(Ca(OH)_2\)) solution, is poured into one of the test tubes and sealed with a stopper. A small amount of hydrochloric acid is carefully poured into the remaining test tube. outback traders vest
