Match the state symbol to the state
When deciding on a separation technique the states of matter will be important.
(aq) + (aq) →(s) Add two solutions then filter, wash and dry the residue.
(s) + (aq) →(aq) Add solid to excess, filter, evaporate the excess water from the filtrate, wash and dry the crystals.
(aq) + (aq) →(aq) Titrate the acid and alkali to determine the volumes of the solutions required, repeat the titration without the indicator, evaporate the excess water and wash and dry the crystals.
