Acid Base Inquiry Project

In conclusion, we found the base identity to be calcium hydroxide through a flame lab, in which we compared the colour of the base flame to calcium nitrate and the colors were very similar, which brought us to our conclusion. For the molar concentration we used a titration lab which used an acid solution and the base, we used a burette to drop amounts of the base into the acid solution which had phenolphthalein as the indicator in it, until the base turned a slight tint of pink. Our molar concentration ended up being 0.04M. Some errors we came could’ve come across is that the equipment was not all properly cleaned and the measurements were off due to old lab equipment, an error we could’ve come across during the titration is that we used the lab we did previously in class which was to find an unknown acid, even though we did the same steps there could’ve been a different way to find the base that we didn’t know about. An error we could’ve come up with during the flame lab is that we used calcium nitrate instead of calcium hydroxide to compare to our base because it was the only option we had. We also might’ve had a better outcome for the titration if we found a lab that was for an unknown base instead of using the one to find an unknown acid.
