identify the color of the solution at the different points throughout a titration between an antacid tablet and naoh if phenolphthalein is used as the indicator. added 5 ml of naoh past the equivalence point beaker contains crushed antacid tablet, water, and excess hcl equivalence point started adding naoh, but not enough to react with all of the acid present colorless pink check answer

identify the color of the solution at the different points throughout a titration between an antacid tablet and naoh if phenolphthalein is used as the indicator. added 5 ml of naoh past the equivalence point beaker contains crushed antacid tablet, water, and excess hcl equivalence point started adding naoh, but not enough to react with all of the acid present colorless pink check answer

Answer

Answer:

  • Beaker contains crushed antacid tablet, water, and excess HCl: Colorless
  • Started adding NaOH, but not enough to react with all of the acid present: Colorless
  • Equivalence point: Pink
  • Added 5 mL of NaOH past the equivalence point: Pink

Explanation:

Step1: Understand phenolphthalein property

Phenolphthalein is color - less in acidic solutions.

Step2: Analyze initial and partial - reaction cases

When there is excess HCl (initial state and partial - reaction state), the solution is acidic, so it's colorless.

Step3: Analyze equivalence and post - equivalence cases

At the equivalence point, the solution is slightly basic due to the nature of the reaction, and phenolphthalein turns pink. Past the equivalence point with excess NaOH, the solution is basic and remains pink.
