Hydrochloric Acid and Magnesium

... t;Mgcl2(aq) + H2(g) 1mole 2moles 1mole 1mole So we can say that one mole of magnesium reacts with 2 moles of hydrochloric acid. We know that the concentration of hydrochloric acid that we start with is 3 moles. Throughout the experiment, we diluted the acid solution using water, as we did this the concentration of the acid decreased. We put the acid(3 moles) into the 10ml testube and then poured the solution into the beaker with the magnesium ribbon init(2cm long) and then measured the time taken for the magnesium ribbon to disappear, using the stop clock. Next, we diluted the acid by placing 9ml of acid and 1ml of water into the testube and then poured it into the beaker with the magnesium and measured the time taken for the magnesium ribbon to disappear using the stop clock. Then 8ml of acid and 2ml of water solution on the magnesium, measured time taken for magnesium to disappear using stop clock . Then 7ml of acid and 3ml of acid, repeated as above . Then 6ml of acid and 4ml of water, repeated as above. We repeated the experiment 3 times to get a fair test by proving that all results are accurate, if they were inaccurate we repeated the experiment again, or ignored wrong results.We tabulated the results in a clear table as soon as each experiment was completed ,in case we lost them and to check for possible errors or gaps in our results and it helped us to spot patterns in the results. We calculated the different, concentrations of the acid throughout the experiment using the ...
