What is/are the product/(s) of the following reaction:

Co(OH)2(s) + OH-(aq) (Eq. 1)

I can inform you of the earlier reaction leading up to this one:

[Co(H2O)6]2+(aq) + 2OH-(aq) rarrow.png Co(OH)2(s) + 6H2O(l) (Eq 2)

The precipitate formed in (Eq. 2) is blue. This precipitate then turns red/grey as conc. NaOH(aq) is added. What is/are the product/(s) formed in equation 1?

Best regards, Shafaifer

Basic conditions. The experiment was not conducted under STP. The temperature in the laboratory that day was 295 - 298 K, I am not sure about the pressure.

Is Eq. 1 wrong (the one Elite Engineer answered)? I got Eq. 2 from a lab manual written and corrected by Ph.d's.
