What is the solubility of water?

  • When a solute is dissolved in a solvent to give a homogeneous mixture, one has a solution.
  • Solubility is generally expressed as the number of grams of solute in one liter of saturated solution.
  • For example, solubility in water might be reported as 12 g/L at 25 oC.

2CuBr + 2OH-   ---> Cu2O(s)  + 2HBr(aq)

adding OH- to the CuBr also shifts the equilibrium to the right side therefore increasing pH will increase the solubility of the CuBr.

An aqueous solution contains the following ions: cl−, ag , pb2 , no−3, and so2−4. More than one precipitate will form. Identify
klasskru [66]

An aqueous solution contains the following ions Cl⁻, Ag⁺, Pb²⁺, NO₃⁻ & SO₄²⁻ and more than one precipitate will form are AgCl, PbCl₂, PbSO₄ & Ag₂SO₄.

<h3>What is precipitate?</h3>

Precipitate is the insoluble compound which is present at the bottom of any chemical reaction in the solid state.

If in an aqueous solution Cl⁻, Ag⁺, Pb²⁺, NO₃⁻ & SO₄²⁻ ions are present then:

  • Compounds AgCl, PbCl₂, PbSO₄ & Ag₂SO₄ are not soluble in water as it is present in the form of precipitate.
  • Pb(NO₃)₂ is fully soluble in water and will not make precipitate.

Hence precipitates are AgCl, PbCl₂, PbSO₄ & Ag₂SO₄.
