A volume of 10 mL of an unknown hydrochloric acid sample was diluted to 100 mL. The diluted solution was then titrated against a solution of sodium carbonate (prepared by dissolving 0.2188 g of solid in 50 mL distilled water). Hydrochloric acid reacted with sodium carbonate according to the following equation: 2 HCI (aq) + Na,CO3 (aq)H20 () + CO2 (g) + 2 NaCl (aq) A volume of 15.2 mL of the hydrochloric acid was required to complete the reaction in the titration process. A second titration was done between the same acid sample against a blank for indicator correction, a volume of 0.3 mL was consumed by the indicator. Find the moles of HCI added and concentration of dilute HCI solution. [MM of Na CO3 = 105.99 g/mol, MM of HCI = 36.46 g/mol] 2.06x10-3 mol ; 0.277 M B 2.06 x10-3 mol; 0.135 M 4.13x10-3 mol ; 0.277 M 4.13x10-3 mol ; 0.272 M
To measure the amount of chlorine in a well-boring fluid, an analytical chemist adds 0.3600M silver nitrate AgNO3 solution to a 24.00g sample of the fluid and collects the solid silver chloride AgCl product. When no more AgCl is produced, he filters, washes and weighs it, and finds that 1.28g has been produced. The balanced chemical equation for the reaction is: Cl−(aq) + AgNO3(aq) -> AgCl(s) + NO−3(aq) What kind of reaction is this? If you said this was a precipitation reaction, enter the chemical formula of the precipitate. If you said this was an acid-base reaction, enter the chemical formula of the reactant that is acting as the base. If you said this was a redox reaction, enter the chemical symbol of the element that is oxidized. Calculate the mass percent of Cl in the sample. Be sure your answer has the correct number of significant digits.
You are carrying out an experiment to determine the MW of a solid acid with the generic formula H3A. You weigh out 0.362 g of the solid acid in a weigh boat and transfer it to a 125 mL Erlenmeyer flask. After dissolving the acid in 25 mL of distilled water, you add 22.51 mL of 0.343 M Sr(OH)2 (aq) solution with a buret until your indicator changes color at the equivalence point. What is the molar mass of the solid acid in units of g/mole? Enter your answer with at least 4 significant digits (Canvas sometimes truncates zeros so assume that all numbers in this question have at least 4 sig figs (ie if Canvas tells you there are 12.3 mL assume 12.30 mL). This question will require precision so don't round any numbers until your final answer.
The concentration of Sn²+ in a solution is determined by titrating it with a 0.1890 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnOq°(aq) + 5Sn²*(aq) + 16H3O*(aq) → 2Mn²+(aq) + 5Sn*(aq) + 24H,O(1) In one experiment, 24.99 mL of the 0.1890-M permanganate solution is required to react completely with 40.00 mL of the Sn2+ solution. Calculate the concentration of the Sn2+ solution. M
