F or each of the following experimental errors clearly state if the error would increase decrease, or have no effect on the percent salt based on the mass of sand recovered that you termined in today's experiment. You must explain your reasoning. (a) Some salt crystals splattered from the evaporation dish while the water was being evaporated from the salt-water mixture. o eet ul hap pen to He Salt percentage The sand was not heated for a long enough time to evaporate all the water. The purcent of Sal+ (b)Explanation / Answer
a) since the salt crystals has splattered from the evaporation dish, the percentage amount of salt that you have recovered is less than expected. So, this error has decreased the salt percent.
b) Since the sand does not dissolve in water and it also is non volatile substance, heating it to either shorter or longer period of time, would not have any effect on the mass of sand recovered.
