- What mass of KHP will be completely neutralized by 32.57 cm33 of 0.175 M standard NaOH solution? The molar mass of KPH is 204.22 g/mol.In the experiment conducted to determine the amount of acetic acid in vinegar, 8.2 mL of NaOH standard solution adjusted to 0.098 M was spent besides the phenolphthaleley indicator. Accordingly, which of the following is the amount of acetic acid in the vinegar sample in grams? (Ma (CH3COOH): 60.05 g / mol)Choi is fond of carbonated beverages so he crafted his own soda formulation called “Sodalicious.” Ulan, who is a fellow enthusiast, also made her own formulation which she called “Soda Pop!” to challenge his friend Choi. To know which formulation is better, they sought to determine the carbonic acid content of their soda formulations using titration. In the first part of their experiment, a 0.5 Mlabeled NaOH solution was standardized against 0.350 grams of KHP (MW = 204.22 g/mol) primary standard that is 99.6% pure. The titration required 3.16 mL of the NaOH solution to reach the phenolphthalein endpoint. In the second part of their experiment, Choi and Ulan independently prepared their samples by taking 25.0-mL of their soda sample and diluting it to 30.0 mL. Using the same titrant and indicator, Choi’s “Sodalicious” required 1.39 mL of the standardized titrant to reach the endpoint, while Ulan’s “Soda Pop!” required 0.926 mL of the same titrant to reach the endpoint.

- To analyze an aspirin sample, 0.3470 g of crushed tablets are weighed and treated with 50.00 mL 0.1155 M sodium hydroxide, boiling for 10 minutes. Under these conditions the acid acetylsalicylic (MW, 180) reacts according to: CH3COO-C6H4-COOH + 2 OH- → OH-C6H4-COO- + CH3COO- The excess NaOH is then titrated with 11.5 mL of 0.2100 M HCl. What is the purity of said show ?.The active ingredient in a certain toilet cleaner that claims to ‘remove lime scale and rust’ is hydrochloric acid of approximate concentration 1.12 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 16.2 mL aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 24.8 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.2178 mol/L. The expected titre (or volume of the titrant) would be approximately:A 0.175 g of primary standard KIO3 requires 11.70 ml of Na2S2O3 solution for titration. what is the molarity of Na2S2O3 solution?
- Given the mole ratio of HCl to NaOH is 1:1 in the balanced acid base reaction A 15.52mL sample of HCl is titrated to endpoint witg a 32.08mL sample of NaOH, which has a known molarity of 0.976M. What was the molarity of HCl?Rei and Akari, two vinegar enthusiasts, are each tasked to determine the aceticacid content of their respective vinegar concoctions by titration. First, a 1M-labeled KOH solution was standardized against the KHP (MW = 204.22 g/mol)standard that is 99.4% pure. In the process, 0.540 g KHP was found to require2.80 mL of the KOH solution to completely react up to the phenolphthaleinendpoint. Then, Rei and Akari both prepared their samples by taking 10.0-mLaliquots of each vinegar and diluting them to 25.0 mL. Using the same titrant andindicator, Rei’s vinegar required 18.60 mL of the standardized titrant to reach theendpoint, while Akari’s vinegar required 16.50 mL of the same titrant to reach thesame endpoint. What is the exact concentration of the KOH titrant in molarity? What is the balanced chemical equation between the analyte and the titrant? What is the color transition (color X color Y) expected throughout thecourse of titration?
