A saturated solution of barium hydroxide is tritrated with 0.0350 M hydrochloric acid. The titration of 15.0 mL of the basic solution required 34.2 mL of the acid solution. Calculate the concentration of the barium hydroxide solution. (plz help i dont get it)
For a titration to be effective, the reaction must be rapid and the yield of the reaction must essentially be 100%. Is Kc > 1, < 1, or ≈ 1 for a titration reaction? Kc is the product of all reaction products (choose from: Multiplied by, added to, divided by, subtracted from) the product of the reactants, with all concentrations of reactants and products raised to their respective stoichiometric powers. As the titration proceeds, the amount of reactants (choose from: Increases, decreases, remains the same) and the amount of products (choose from: Increases, decreases, remains the same). Because the value of the numerator is (Choose from much greater than, much less than, approximately equal to) the value of the denominator, the value of Kc will be (Choose from much greater than, much less than, approximately equal to)1 for an effective titration reaction.

Reaction A Sodium Sodium Acetic acid Water hydroxido acetate Use the titration data to calculate the molarity of acetic acid in the vinegar. Try a sample calculation Refer to Section 4 for sample calculations: A 5.00 ml sample of vinegar was titrated with 0.08751 M N2OH. The sample requires 22.31 mL of NAOH to reach the endpoint. Calculate the molarity of the acetic acid (CH,COOH) solution in the vinegar sample. The density of the vinegar solution has been determined to be 1.0052 g/ml. If the vinegar is being manufactured, and is supposed to have a molar concentration between 0.45 and 0.60, can this batch be sold?
