. You transfer 25.00 mL of your Kroger brand vinegar solution via volumetric pipet to a 250.00 mL volumetric flask and dilute to the final volume using distilled water, after which you mix the solution well. Next, you take a 25.00 mL aliquot of this diluted commercial vinegar solution and transfer it to a 150 mL Erlenmeyer flask. Titration of this sample to the phenolphthalein endpoint with sodium hydroxide required 15.81 mL of the 0.1002 M NaOH titrant. Based on this data, what is the molar concentration of the acetic acid in the original Kroger brand commercial vinegar solution ?

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
