Which antacid is most effective science project?
Having completed this experiment, students then determined the average volume of acid neutralized per gram of antacid to determine which was the most effective. After all of their hard work, students found that Pepto-Bismol was the most effective at neutralizing acid.
How do you test for antacids?
Label each test tube with the name of one of the liquid antacids you are testing. Add the first antacid, drop by drop, to the first test tube. Stop as soon as the solution changes colors. A color change means that the antacid has neutralized the acid in the lemon juice.
What are antacids class 10 science?
What are antacids? Antacids are mild alkalies and contain sodium hydrogen carbonate. These are used for getting relief from acidity and indigestion and sometimes, even headache. When taken orally, it reacts with hydrochloric acid present in the stomach and reduces its strength by consuming some of it.
What is the science behind antacids?
Antacids work by counteracting (neutralising) the acid in your stomach. They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids. A reaction between an acid and base is called neutralisation. This neutralisation makes the stomach contents less corrosive.
What is the independent variable in antacid experiment?
All Science Fair Projects For this experiment, the independent variable is the brand of antacid. The dependent variable is the amount of acid needed to neutralize the antacid. This is determined by measuring the amount of acid dropped from the burette, and by using a pH meter.
What is the pH of stomach acid?
1.5 to 3.5
Normal Results. The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). These numbers are converted to actual acid production in units of milliequivalents per hour (mEq/hr) in some cases. Note: Normal value ranges may vary slightly depending on the lab doing the test.
What are antacids chemistry class 12?
Antacid is a medicine used to neutralise the stomach acid in order to cut down the burn we have during acidity. Stomach produces acid and to neutralise it, we need a base. So, antacids are basically a base.
What is antacid formula?
The chemical formula for the substance which are used as antacid Calcium hydroxide Ca(OH)2 is an example of antacid.
What are antacids in chemistry?
Antacids are relative simply assembled salts and salt-like compounds which neutralize acids. This neutralization reactions lead to several products (other salts, water, and possibly carbondioxid), resulting in steps, like hydrolysis and precipitations of insoluble compounds.
