Sodium carbonate, Na2CO3, reacts with hydrochloric acid, HCl, to produce sodium chloride, carbon dioxide and water. Refer to slide 7.18 for a summary of formulae relevant to the calculations below. 2HCl(aq) + Na.CO3(aq) + NaCl(aq) + H2O(l) + CO2(g) 1. Use this reaction to explain what is meant by the terms "acid", "conjugate base" and "salt" 2. Balance the equation for this reaction. 3. A solution was prepared by dissolving 5.00 g of Na2CO3 in water and adding water to...
Sodium carbonate (MM=105.988 g/mol) is a primary standard base that reacts with hydrochloric acid as follows: Na2CO3 + 2HCI → 2NaCl + H2O + CO2(g) If 39.09 mL of an HCl solution were required to titrate a solution containing 287.5 mg of primary standard Na2CO3, calculate the molarity of the HCl solution.
Solution Stoichiometry Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) a) What volume of 2.75 M HCl in liters is needed to react completely (with nothing left over) with 0.750 L of 0.300 M Na2CO3? b) A 565-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 10.1 g CO2. What was the concentration of the HCl solution? How do I...
The molar mass of sodium carbonate is 105.9888 g/mol. A student weighs out 0.2211 g of it to standardize their HCI solution. The initial reading is 0.23 mL and the final is 41.82 mL. Fill in the missing conversions to determine mols of acid titrated: What is the volume HCI titrated? What is the molarity of the HCI titrated?
4. Sodium carbonate (Na:CO) is available in a very pure form and can be used to accurately determine the concentration of an acid solution by titration. This process is called standardization. (15 points total) a. Write a balanced equation for the neutralization of the strong acid HCl by sodium carbonate. The products are a salt, carbon dioxide and water b. You perform a titration experiment and discover it takes 0.265 g of Na:CO, (molar mass 105.99 g/mol) to neutralize 28.3...
A 0.6739 g sample of a pure carbonate, X,CO,(s), was dissolved in 50.0 mL of 0.1850 M HCl(aq). The excess HCl(aq) was back titrated with 24.70 mL of 0.0980 M NaOH(aq). How many moles of HCl react with the carbonate? moles of HCI = mol What is the identity of the cation, X? cation: A standardized solution that is 0.0100 M in Na+ is necessary for a Hame photometric determination of the element. How many grams of primary-standard-grade sodium carbonate...
