Copper(I) chloride is a slightly soluble salt. The copper(I) ion also combines with Cl- in excess chloride to form the complex ion CuCl2-. Calculate the molar solubility of CuCl(s) in 0.0667 M KCl.
Use the values of equilibrium constants given in your text.Assume the Keq values are exact numbers, so that the number of significant figures in your final result is based on the concentration of KCl.
A solution of chloroform (CHCL3) in carbon tetrachloride (CCL4) is 1.87 molar chloroform and has a density of 2.93 grams/mL. Calculate
The CNOG ion is very unstable and is the reason why the mercuric compound is explosive. On the other hand, mercury cyanate, Hg(NCO)2, is not explosive. The cyanate ion (NCOG) is a stable ion. Use resonance structures and electronegativities to exp..
