What change is needed to obtain purer carbon monoxide? A Use sulfuric acid instead of hydrochloric acid to prevent hydrogen chloride formation. B Pass gas stream from X into a flask containing a drying agent before collection. C Pass gas stream from X into a flask containing aqueous sodium hydroxide before collection. D Pass gas stream from X through a filtering device to remove soot produced from the charcoal. 2 A student wants to separate a mixture of sodium ethanoate and calcium sulfate. Which sequence shows the correct steps for separating the mixture?
