Sodium Carbonate → Cerous carbonate

関与物質

反応手順

Colloid preparation: the solution of cerium nitrate and the solution of sodium carbonate are simultaneously dropped in one beaker at 55° C., PH=9 to obtain an alkali cerium carbonate colloid. The colloid was washed 5 times with distilled water. If the above solution of sodium carbonate is replaced by the solution of potassium carbonate, ammonia, sodium hydroxide and/or potassium hydroxide as precipitator, the corresponding colloid or precipitates will be obtained.
