Question

Titration of an Antacid (i.e., an anti-acid, in other words a base) Part A Procedure: 1. To a beaker of appropriate size add 190 mL of distilled water. Afterwards, using your 10 mL graduated cylinder, add 10 mL of 4 M HCl (hydrochloric acid) stock solution (CAUTION - STRONG ACID-CORROSIVE!) to the 190 mL of distilled water. Mix the solution well. Using a Rainin pipet, carefully pipet 10.000 mL (two 5.000 mL portions with the Rainin pipet) of your just prepared HCl solution into three separate 250 mL Erlenmeyer flasks (DO NOT USE BEAKERS!) and add 3 drops of phenolphthalein indicator to each Erlenmeyer flask. Note: The 5.00 mL setting on the Rainin pipet looks like this: lololul - 2. Clean and fill your buret (using the same procedure you used last week) with your 0.0967 M NaOH solution (CAUTION - STRONG BASE - CORROSIVE!) stored in your screw-cap 1 L drinking water bottle. Record the initial and final buret readings for each of the three trials as you titrate the HCl solution with your NaOH solution to the phenolphthalein end point (a light pink). 3. Afterwards, calculate all the other quantities specified in your data sheet. Part B Procedure 4. Record the mass of one tablet of Acme's new Belly Bliss antacid. Grind the Belly Bliss tablet to a fine powder in a clean mortar and pestle. Weigh out three approximately 0.400 g samples of crushed Belly Bliss and place them into three separate 250 mL Erlenmeyer flasks (DO NOT USE BEAKERS!). Record the exact weights. 5. Using your 100 mL graduated cylinder, carefully measure out and add exactly 25.00 mL of your prepared HCl solution to each Erlenmeyer flask. Add approximately 75 mL of distilled water to each Erlenmeyer flask, then heat each flask to boiling on a local hot plate. After the samples have boiled for about one minute, take them off the hot plate and add 3 drops of phenolphthalein indicator to each Erlenmeyer flask. Page 1 of 5

This is all the information I have. Any Help would be appreciated.
