If a student doesn't add enough HCI to dissolve all of the excess zinc, what effect will this have, if any, on the %Cu that is calculated for the copper(II) sulfate pentahydrate? the calculated %Cu will be higher than actual the calculated %Cu will be lower than actual more information is needed to answer this question no error is created since zinc is not copper and doesn't add to the copper mass If a student's filter paper tears and some of their copper remains in the filtrate solution, what effect will this have, if any, on the %Cu that is calculated for the copper(II) sulfate pentahydrate?
