A mineral sample is analyzed for its cobalt and calcium content. A sample is dissolved, and then the cobalt and calcium are precipitated as co(oh)2(s) and ca(oh)2(s). At what ph can co(oh)2(s) be separated from ca(oh)2(s) at 25 °c? assume that an effective separation requires a maximum concentration of the less soluble hydroxide of 1×10−6 m.
