You want to determine the % of an acetic acid sample solution by acid/basetitration. Therefore, you prepare a NaOH solution. To determine the exactconcentration of this NaOH you titrate exactly 390.3 mg KHPhthalate(M = 204.22 g/mol) with this NaOH solution requiring 8.2 ml. Subsequently youuse this NaOH solution to titrate 25.0 ml of your acetic acid sample(M(acetic acid)=60.05 g/mol, density of solution 1 g/ml) resulting in a consumptionof 6.9 ml of the NaOH solution.=Please give all relevant reaction equations (with correct stoichiometry).Calculate the exact concentration (in mol/L) of the NaOH solution.Please calculate the weight-% of acetic acid in the sample solution.Which indicator would you use for this titration/at which pH range would youexpect the equivalence point?

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.

In your kitchen, you have a vinegar bottle that indicates that it has 5% vinegar. As you wanted to see if this claim is true. You decided to do a quantitative analysis u Let's assume that you are performing an experiment in a laboratory and have all for this titration. You have collected following information. Volume of the acetic acid (CH3COOH)use for the titration = 25.0 mL Morlarity of the NaOH solution = 0.90 M Initial burette reading = 22.82 mL Final burette reading = 45.67 ml Assume density of the vinegar solution is same as the density of water (1.0g/mL) Using above information how do you prove or discard above claim (5% vinegar).
