Also if you measured the wrong data that would change the mass of the NaCl which would change the ratio.  Also, when the test tubes were in the oven there could have been water still in the test tubes when we took them out and that could relate to higher ratios. Lastly, if NaHCo3 didn't react completely it would decrease the mass of NaCl which would decrease the ratio.

This will either increase or decrease the end result of the moles of sodium bicarbonate as well as the mole ratio. 

Another example could have been adding too much sodium bicarbonate. By adding more sodium bicarbonate the reactions to the HCl would've lasted much longer which eventually would change the quantity of the products after a night in the oven.   ]]> 2018-02-28 17:19:28 UTC https://padlet.com/zak_johnson/8a4vbdnjjm2d/wish/236534008 https://padlet.com/zak_johnson/8a4vbdnjjm2d/wish/236536610 Because we want to fasten the  lab, which was making the baking soda dissolve quickly. We wanted to put in more of HCl.
This resulted in chemical action with bubbles that were formed. It caused the substance to over flow out of the test tube, which decreased the amount of the water and salt.  So the ratio will decrease because the amount of the NaCO3 didn't changed and the amount of salt has been decreased.

Another problem is too much liquid was added to the tube, so there was too much liquid that needed to be evaporated in short amount of time. So it increased the mass of the salt, because there is excess water in the mass, and the amount of the NaCO3 is sustained.]]> 2018-02-28 17:23:19 UTC https://padlet.com/zak_johnson/8a4vbdnjjm2d/wish/236536610 https://padlet.com/zak_johnson/8a4vbdnjjm2d/wish/236540422 The major error that occured in this lab was the overflow of the solution. This was due to the excessive amount of HCl, also known as hydrochloric acid, reacting with the NaHCO3, also known as sodium bicarbonate or baking soda. This overflow caused an increase of CO2, also known as carbon dioxide, to be released from the reaction seen as bubbles pushing up the solution containing NaCl and H2O; The solutioning coming out of the test tube affected the masses and rations. The mass of NaCl was decreased based on the amount of solution that was spilled causing for the ratio between sodium chloride (NaCl) and sodium bicarbonate (NaHCO3) to decrease.]]> 2018-02-28 17:28:40 UTC https://padlet.com/zak_johnson/8a4vbdnjjm2d/wish/236540422
