In the NJCTL reference table for solubilities, Ca(OH)2 is 'S' meaning soluble, however it is actually sS. This makes the answer key #50 incorrect (Double Replacement Reactions Classwork). Please revisit the table. The solubilities table does not mention compounds of Pb and Co.

Rupa - thank you for pointing this out. It has been corrected and a new reference sheet has been posted at this link: https://njctl.org/materials/resources/chemistry-reference-sheets/attachments/ - Melissa
