(1) (a) and (b) are elements that belong to period 5 and 6 in the periodic table, respectively. Both simple substances are solid under room temperature. To an aqueous solution containing cations of (a) and (b), dilute hydrochloric acid was dropped to produce white precipitate. Upon rinsing with boiling water, the precipitate was partially dissolved. (2) Both (c) and (d) are elements that produce stable trivalent cations in an aqueous solution. To an aqueous solution containing (c) and (d) as trivalent cations, aqueous ammonia was dropped to produce a gel-like precipitate. Upon the addition of concentrated aqueous sodium hydroxide, the precipitate was partially dissolved and the majority of ( c) was transferred to the supernatant.
