Experiment 12 THE DETERMINATION OF THE NEUTRALIZING ABILITY OF ANTACIDS The Pre-Lab 1. A 1.032 gram sample of an antacid was dissolved in 50 mL of water. Then a 49.33 mL portion of 0.488 M HCI was added to the flask. The antacid was completely neutralized and the unneutralized hydrochloric acid remaining in the flask...

A vitamin C (ascorbic acid) tablet was dissolved in approximately 50 mL of distilled water and titrated with the standardized NAOH solution. From the results of this titration, the mg of ascorbic acid in the tablet was calculated. Molecular formula of ascorbic acid: C6H806 Volume of NaOH required to neutralize ascorbic acid in Vitamin C tablet (mL) 14.47 Concentration of NaOH in mol/L, 0.1964 Calculate the amount of ascorbic acid in the Vitamin C tablet in (mg).

Questions, please
An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...

Below is a lab hand out for the questions. All my data for the questions are filled out below in BOLD LETTERING. All the questions I need answered are at the bottom with boxes where to put the answers. Background Alka-Seltzer� is an over-the-counter antacid and pain relief drug. The tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate (NaHCO3). Sodium bicarbonate (NaHCO3) is responsible for the effervescent action of Alka-Seltzer. In this lab we will investigate the reaction...
