MY FIRST EXPERIMENT

At our most recent class, we obtained pure hydrogen

For conducting an experiment, we required certain equipment

We used a variety of glassware or tableware such as test tubes , flasks ,mugs, jars ,rod and tube

Before reacting,the students weighed the substance on a scale

I put metallic zin in a round –bottomed flask and started adding a few drops of hydrochloric acid

Then we put a burning match at the top of the flaslk

I saw blue flames. This is the fact that we got pure hydrogen or combustible air

We observed the reaction and recorded the yield

At the end of the rection ,all plates were washed and set right place

Thank you for your attention
