A ph is a -log(h3,0+). An indicator is a weak organic acids whose color differs from that of its conjugate.A buffer is a soluton that can receive moderate amounts of either acid or base without significant change in its ph. Neutralization is combinig equation with one dimension of order.
My hypothesis is that the tums will get rid of more acid. The different antacids that im testing are tum, meijer tums, rolaids, meijer rolaids, and meijer alka seltzer.
Prepare 300 ml of a 0.1 M HCL solution. Prepare antacid mixture by dissolving two tablets of each in 150 mL of distilled water in a 250 mL beaker. Stir the antacid mixture and tranfer 50mL of the mixtuer to a 250 ml Erlenmeyer flask for each trial. Clean the burets .pour 50 mL of 0.1 M HCL into a small beaker and use it to fill the buret. Add five drops of universal indicator to the Erlenmeyer flask containg the antacid mixture .titrate
the antacid solution with the HCL solution until the antacid turn pink or red. Record your data in your dat table. Repeat steps one though eight one or two times.
For the tums the result was 1.00. the meiljer tums had the same results. This was because they both have the sam chemicals in them. CaCO3 is not a very strong base at all. The amount the was used were 500 mg of CaCO3.
For the rolaids the results 3.3. the meijer rolaids was different because the rolaids has 550 mg of CaCO3 and 110 mg Mg(OH)2. While the meijer rolaids are different. It has 412 mg CaCO3 and 80 mg of Mg(OH)2.
Meijer alka seltzer result was 34.2 it is the best antacid becaus eit has the strongest base in it it contain 1000...
