Lab Titration of Acids and Bases 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way you used KHP in this experiment. In such a standardization, it was found that a 0.512 sample of sodium carbonate required 26.30 mL of a sulfuric acid solution to reach the end point for the reaction. Na CO2(aq) + H2SO (aq) →H2O(1)+ CO2(8)+ Na 50 (aq) What is the molarity of the H,SO 2 6. A solution...
Sodium carbonate (Na2CO3) is available in very pure form and can be used to standardize acid solutions. What is the molarity of an HCl solution if 31.3 mL of the solution is required to react with 0.256 g of Na2CO3? ______________M
1. A student is asked to standardize a solution of sodium hydroxide. He weighs out 0.960 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid). It requires 18.1 mL of sodium hydroxide to reach the endpoint. A. What is the molarity of the sodium hydroxide solution? ___M This sodium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid. B. If 12.8 mL of the sodium hydroxide solution is required to neutralize 27.8 mL of...

Potassium hydrogen phthalate (KHP) is used to standardize sodium hydroxide. If 15.18 mL of NaOH(aq) is required to titrate 0.5614 g KHP to the equivalence point, what is the concentration of the NaOH(aq)? (The molar mass of KHP = 204.2 g/mol) HCH,0, (aq) + OH (aq) SCH,02 (aq) + H,0(1)
A 1.2485 g sample of CaCO3 is used to standardize an EDTA titrant. The CaCO3 was dissolved in water and buffered to pH = 9.0. It required 39.53 mL of EDTA to reach the end point. Calculate the concentration of the EDTA (in molarity). - please show work -
A 1.2647 g sample of CaCO3 is used to standardize an EDTA titrant. The CaCO3 was dissolved in water and buffered to pH = 9.0. It required 46.94 mL of EDTA to reach the end point. Calculate the concentration of the EDTA (in molarity). Express the answer with 4 decimal places.
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...
