A solution contains 0.0022 M Ag⁺ and 1.6 x 10^-5 M Zn²⁺, and the ions need to be separated. For this purpose is added to the solution so that both Ag₂CO₃ (K_sp = 8.1 x 10^-12) and ZnCO₃ (K_sp = 1.0 x 10^-10) can precipitate from the solution.

What will the concentration of be just before the first salt starts to precipitate? (Please give your answer with 2 significant figures.)

'n Oplossing bevat 0.0022 M Ag⁺ en 1.6 x 10^-5 M Zn²⁺ en die ione moet geskei word. Hiervoor word by die oplossing gevoeg sodat beide Ag₂CO₃ (K_sp = 8.1 x 10^-12) en ZnCO₃ (K_sp = 1.0 x 10^-10) kan neerslaan vanuit die oplossing.

Wat sal die konsentrasie van wees net voordat die eerste sout begin neerslaan? (Gee asb jou antwoord met 2 beduidende syfers.)
