Question

Which of the following would decrease the K_sp for PbI_2? Adding a solution of Pb(NO_3)_2 Adding a solution of KI Lowering the pH of the solution None of the above-the K_sp of a compound is constant at constant temperature. Which one of these salts will form an acidic solution upon dissolving in water? NaCN NH_4Br LiBr NaF KOH What is the solubility product expression for Zn_3(PO_4)_2? K_sp =[Zn^2+ ][2PO_4^3-] K_sp =[3Zn^2+ ]^3 [2PO_4^3-]^2 K_sp =[Zn_3^2+ ][(PO_4^3-)_2] K_sp =[Zn^3+ ]^2 [PO_4^2-]^3 K_sp =[Zn^2+ ][2PO_4^3-]^2

Explanation / Answer

93.

none, since Ksp is aconstant, it changes only with T

that is why we use the name "constant" what we change is the quotienet "Q"

94.

acidic --> H+ rich

then

choose a weak base + strong acid titration

this is

NH4Br --> NH4+ + Br-

NH4+ + H2O <--> NH3 + H3O+ which is acidic

95.

Zn3(PO4)2 <--> 3Zn+2 + 2PO4-3

Ksp = [Zn+2]^3 [PO4-3]^2
