Zinc and Hydrochloric-AcidAbstractWe observed the reaction between atomic number 30 and hydrochloric acid and recorded it in a table and learned wether the helping of atomic number 30 is effected by the amounts of both substances added to the solution. IntroductionThe purpose of this taste is to determine if the amount of zinc and hydrochloric acid go out effect the parting of the zinc in the appear coming solution. We ar reacting zinc coat with hydrochloric acid to produce a compound of zinc and chlorine atoms. We are then recording our data and observations and place it in a analytical data table.Purpose The whole purpose of this experiment is to determine wether or not the amount of the zinc and or hydrochloric acid effects the out coming percent of the solution after under going chemical reaction.Procedure$     1. Weigh the zinc metal pieces and place them in a test subway$     2. Pour some hydrochloric acid over the zinc pieces . Observe$     3. Allow the zinc d hydrochloric acid to set over night to make sure that the reaction reaches completion.$     4. Weigh a change dry evaporating truelove.$     5. Decant the liquid remaining in your test pipage into the evaporating dish.$     6. Pour 2-3 ml distilled or de-ionized water into test resistance and sponge any remaining zinc with water and decant the water into the evaporating dish also. If you contract no remaining zinc pieces, rinse the test tube and decant the liquid into the dish.$     7. Heat the evaporating dish until there is no to a greater extent liquid remaining in the dish. The solid remaining will have a puffy and waxy look. Do not overheat moreover remove from the hot plate and turn off the heat line of descent because the product has a relatively low melting point and it will melt and evaporate away in a white smear$   &nb sp 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 comparison with other lab groups.Data and ObservationsI observed that as the chemicals reacted together in the test tube the solution began to create bubbles trance the zinc rested at the bottom and then the test tube became hot to the touch from the chemical reaction.
