Sodium Carbonate → Chromium(3+) carbonate (2/3)

Participants

Reaction Steps

731 g of a 20% aqueous solution of potassium carbonate was used instead of the 10% aqueous solution of sodium carbonate used in Example 1, and was simultaneously added with chromium chloride at an addition speed of 14.6 g/min. The pH of the reaction liquid was maintained at about 8. Except these, a light blue chromium (III) carbonate powder was obtained as in Example 1. Measurement as in Example 1 was performed for the obtained chromium (III) carbonate. The results are shown in the following Table 1.
