For each statement choose whether it is True or False. a. Decanting is a separation technique where you want to keep the liquid/aqueous phase of the product. False b. An evaporating dish could be used to recover or even dry a solid product. True C. Assuming no calculations errors, if the percent recovery was < 100% it could be due to loss of copper left in aqueous phase copper compounds. True d. Assuming no calculations errors, if the percent recovery was > 100% it could be because unreacted zinc is still left in the evaporating dish. True
