Forgetting to zero the scale affects the whole lab because measurements will be off. Getting the mass of the baking soda/salt also makes an error in the lab. Having an incorrect mass will cause the ratio to be off, making the final product be false. Another error could be not adding enough hydrochloric acid. This would cause the lab to be inaccurate because the ratio wouldn't be completed. If the reaction didn't happen, it would not turn into salt and the mass would wrong, making the ratio bigger and incorrect. ]]> 2018-02-28 13:38:43 UTC https://padlet.com/zak_johnson/q3xztmuunxbu/wish/236371391 https://padlet.com/zak_johnson/q3xztmuunxbu/wish/236371733 One of the errors that was made in the experiment was that a group memeber accidently spilt some of the sodium bicarbonate and hydrochloric acid solution while he was gently shaking the test tube from side to side. Some of the solution was lost when it spilt on another group members paper. This effected the end result by increasing the mole ratio. The second mistake the group made was not putting enough HCl in the test tube for the reaction. This effected the outcome of the experiment because there was less salt, and the ratio was lowered because of that. ]]> 2018-02-28 13:39:22 UTC https://padlet.com/zak_johnson/q3xztmuunxbu/wish/236371733 https://padlet.com/zak_johnson/q3xztmuunxbu/wish/236371946 A possibility of not letting the chemical reaction finish could cause less salt to be produced. If the reaction is incomplete, the mole ratio will not be exactly 1:1. Another possibility we could have split the liquid affecting the amount and the result changing the ratio once more. When pouring NaHCO3 solution into the tubes, there might be too much of the aqueous solution. It might make the 1:1 ratio larger . Finally if the scale was not zeroed out every time the measurements taken of baking soda and salt would not be precise once again causing for a drastic change in the mole ratio.

This caused the salt to form weirdly.]]> 2018-02-28 13:40:34 UTC https://padlet.com/zak_johnson/q3xztmuunxbu/wish/236372284
