If you combine KSOs(aq) and AgNOs(aq) and the solution becomes a very cloudy white, what compound forms the precipitate? Write the balanced molecular equation and the net ionic equation for the reaction of NaCl(aq) and AgNO3(aq) c. 12. You have a piece of metal, a graduated...
Suppose you have an unknown clear, colorless solution. In attempt to identify it, you add NaOH dropwise and find that a white gelatinous precipitate forms, but when more NaOH was added the precipitate dissolved again. To another test tube of the same unknown solution is added AgNO3 dropwise, and a white precipitate forms. What salt most likely comprises the unknown solution? Explain your reasoning.

I need help please To a solution containing 0.15 M Ci- ion and 0.15 M Br- ion, you add some solid AgNO3. Ksp for AgCl is 1.6 * 10^-10 and for AgBr is 5.0*10^-13. the addition of solid doesn't change the total volume. a) which component AgCl or AgBr precipitates first? b) what is the concentration of the first anion to precipitate when the silver halide of the second anion starts to precipitate?
Introduction The chemical reactions involved in this experiment are: CuSO4(aq) + Zn(s) → ZnSO4(aq) + Cu(s) Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g) The copper on the surface quickly reacts with oxygen according to the following reaction: 2Cu(s) + O2(g) → 2CuO(s) Experimental Procedure Dissolve completely about 0.5 to 0.7 g of copper (II) sulphate pentahydrate in about 10 to 20 mL of deionized water. Calculate the amount of zinc powder that must be added to a copper sulfate solution...
