PLEASE ANSWER A B C D AND E You add Hydrochloric Acid to distilled water. If all the HCl dissociates in solution, calculate the pH of the final solution given the following data. (assume the liquid volumes are addative) You weigh a sample of a monoprotic unknown acid and dissolve it in 50.00 mL of distilled water. Exactly half of this solution is titrated with Sodium Hydroxide to the phenolphthalein end point. The pH of the other half of the original solution is measured with a pH meter. The "neutralized" solution is added to the "original" solution and the pH of this combined "final" solution is also measured. The following are the measured values: CALCULATE the following (a) Molecular Weight of Acid used in titration ___ (b) Molarity of UNKNOWN Acid solution from titration ___ (c) Ka of UNKNOWN Acid ___ (d) Concentration of undissociated Acid from pH measurements ___ (e) Total concentration of N acid from pH measurements ___
