Compare the processes that occur when hydrogen chloride (HCl), dissolve in water. What would the equation be and how would you draw a sketch showing the form in which the compound is present in its respective solution.
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.
