 * __Aim:__** to separate the hydrogen and clorine in hydrocloric acid by adding magnesium to harvest the hydrogen gas.


 * __Hypothesis:__** hydrogen gas will be collected by adding magnesium to the hydrocloric acid taking gas in a testube, when the match is lite over the gas the match will ignite the gas, and make a big pop.


 * __Equipment:__**
 * test tube x2
 * matches
 * hydrocloric acid
 * magnesium
 * test tube rack
 * __Safety precautions:__**
 * apron
 * glasses
 * covered shoes e.g. no thongs, yes snickers


 * __Method:__**
 * 1) collect and set up your equipment
 * 2) squirt hydrocloric acid in test tube (test tube is in the rack)
 * 3) get magnesium and put it into the acid, quickly put the 2nd testube on the top of the 1st test tube seal it with fingers
 * 4) wait until the magnesium is disovled
 * 5) lift the test tube off the bottom one, get your to lit a match
 * 6) slowly turn the test tube upwards with the match at the end of the test tube

the results were that there was a big pop and hydrocloric acid was collected and it was proved by the big pop. the pop was because the match had ignited. when the magnesium was put in to the hydrocloric acid it got hot and the acid started bubbling.
 * __Results:__**

the hypothesis was correct it did make a pop and the gas was ignited.
