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.

Na 2 S Correct Answer: Option B Explanation No official explanation is … WebSecondary copper sulfide enrichment is widely accepted today as resulting from oxidation of copper sulfide minerals, downward migration of soluble copper sulfates, and precipitation as copper sulfide by reaction with primary sulfide minerals. Chalcopyrite is replaced preferentially to pyrite. nes black cartridge
What happens when copper sulphate is mixed with water?
WebThis high solubility is a result of oxidative dissolution of Cu x S y, formation of relatively more soluble copper sulfate hydroxides, and the formation of small CuS nanoclusters that … WebThe sulfide solubility chart below demonstrates the solubility of the metal sulfide compounds. Copper sulfide, for example, is a very insoluble compound and the presences of soluble sulfide precipitates the copper as it dissociates from the ammonical complex. Ultimately, the copper is all removed from the complex and precipitated as copper sulfide.
