Zinc and Hydrochloric-AcidAbstractWe spy the reaction among coat and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is returned by the amounts of both substances added to the solution. IntroductionThe blueprint of this experiment is to tick if the amount of zinc and hydrochloric acid go out effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric acid to produce a composite of zinc and centilitre atoms. We are then recording our data and observations and place it in a logical data table.Purpose The whole purpose of this experiment is to determine wether or not the amount of the zinc and or hydrochloric acid personal effects the out coming percent of the solution after under all overtaking chemical reaction.Procedure$1. Weigh the zinc metal pieces and place them in a runnel organ pipe$2. Pour some hydrochloric acid over the zinc pieces. Observe$3. Allow the zinc d hydrochloric acid to make up over night to make sure that the reaction reaches completion.$4. Weigh a clean dry evaporating dish.$5. Decant the liquid remaining in your evidence tube into the evaporating dish.$6. Pour 2-3 ml distilled or de-ionized pissing into visitation tube and rinse any remaining zinc with water and decant the water into the evaporating dish also. If you have no remaining zinc pieces, rinse the test tube and decant the liquid into the dish.$7. Heat the evaporating dish until there is no more liquid remaining in the dish. The solid remaining will have a puffy and waxy look. Do not hot up but remove from the hot plate and turn off the shake up source because the product has a relatively low melting record and it will melt and evaporate away in a blank cloud$8. When th evaporating dish has cooled sufficiently, weigh the dish with its contents.$9. Clean up by washing and drying your evaporating dish.$10. Calculate and report your % zinc in the compound to your teacher for co mparison with other lab groups.Data and ObservationsI observed that as the chemicals reacted together in the test tube the solution began to give bubbles while the zinc rested at the bottom and then the test tube became hot to the touch from the chemical reaction.
