Antacid

Ant pane Aim: The aim of this try out was to gradation how much gastric antagonistic in needed to annul some hydrochloric acid. Materials: ·         Dilute hydrochloric acid ·         A little(a) flask ·         50mL measuring stick cylinder ·          methyl group orange indicator ·         Spatula ·          gastric antacid powder ·         Small intentionable cupful ·         A relief mode: A small tally of antacid was shovelled into the small cup. aft(prenominal) this the mass of the cup and antacid was weighed and recorded. A measuring cylinder was employ to measure 50mL of dilute hydrochloric acid, which was later pou scarlet into the flask. round 3 to 4 drops of methyl orange indicator was to a fault added to the flask. Ten scoops of antacid were employ to achieve the desired effect, which was to turn the colour of the wate r from red to yellow. After the water had off-key yellow the remaining antacid was weighted and subtracted from the original amount of antacid. The results were recorded. Results: Mass of the cup and antacid = 1.4 + 1.87 = 3.27- 1.21 ( the weight of the extra cup ) = 2.06g Number of Scoops used = 10 Mass of cup and antacid left =1.

81g Antacid used = 2.06 ? 1.81 = .25g Conclusion: In this experiment I gained knowledge of the use of antacid and how it works. I alike witnessed an extreme colour change, which happened in a matter of seconds after(prenominal) the tenth scoop was added. another(prenominal) first was the use of the scientific balance that proved in truth useful for my knowledge and ! to a fault proved useful end-to-end the experiment.
