My first experiment

Last week our group conducted a very interesting experiment on chemistry. We obtained pure hydrogen at our last lesion. For conducting an experiment we needed different apparatus. We used various glassware or dish such as test – tubes, bottles, flasks, funnels, beakers, glasses, rods and tubes. Before the reaction the students weighed substances on the scales, We needed some metals and acids. Then we put some metallic zinc into the round - bottom flask and began to add some drops of hydrochloric acid. Then we put a burning match at the top of the flask.

We saw a blue flame that was a fact that we obtained pure hydrogen or inflammable air. We observed the reaction and recorded the yield.

At the end of the reaction we washed all dishes and put them on proper places.
