How to make a project on comparative study on antacids?

Answer 1

· Prepare half litre of N/10 HCl solution by diluting 10 ml of the concentrated acid to 1 litre.

· Prepare N/10 sodium carbonate solution by weighing exactly 1.325 g of anhydrous sodium carbonate and then dissolving it in water to prepare exactly 0.25 litre of solution.

· Standardize the HCl solution by titrating it against the standard sodium carbonate solution using methyl orange as indicator.

· Take 20 ml of standardized HCl in the conical flask, use methyl orange as indicator and see the amount of base used for neutralization.

· Powder the various sample of antacids tablets and weigh 10 mg of each.

o Take 20 ml of standardized HCl solution in the conical flask; add the weighed samples to it.

o Add two drops of methyl orange and warm the flask till most of the powder dissolves. Filter off the insoluble material.

o Titrate the solution against the standardized Na2C03 solution till a permanent red tinge appears.

o Note the amount of base used for titration and note the reduction in the amount of base used.

o Repeat the experiment with different antacids.

Answer 2

To make a project on a comparative study of antacids, you can select different types of antacids available in the market, research their active ingredients, dosage forms, effectiveness in neutralizing stomach acid, side effects, and cost. Conduct experiments to compare their pH levels after interaction with acid, analyze the results, and draw conclusions on which antacids are most effective. Present your findings in a report highlighting the differences between the antacid products.
