Solubility of copper sulphide

WebFor ionic compounds with limited solubility in water, an equilibrium constant, K sp, can be defined from the ion concentration in water from the equation:. M m A n (s) = mM n+ (aq) + nA m-(aq). where M m A n is the slightly soluble substance and M n+ and A m-are the ions produced in solution by dissosiation of M m A n.. K sp = [M n+] m * [A m-] n. The table … Webthe copper sulphide particles produced immediately after precipitation. Figure 3 shows the effects of S2-ion concentration on both zeta potential and settleability of copper sulphide particles. The data points corresponding to 0 mg.l-1 of S2-ions in Figure 3 are the same data points corresponding to 0 mg.l-1 of Cu2+ ions in Figure 2.
