Answer to Question #108217 in General Chemistry for kiara

Question

Determine whether each of the following ionic substances is highly or slightly soluble in
water. For those that are highly soluble write their dissociation equations and calculate the
concentration of the ions assuming all solutions are 0.75mol/L
a) CaCO 3 b) AgBr
c) NaNO 3 d) CuCl
e) NaCH 3 COO f) AlPO 4
g) CuS h) Pb(SO 4 )

Answer 1

a) insoluble

b) insoluble

c)soluble

NaNO₃ --> Na⁺ + NO₃^- ;

[Na⁺]=[NO₃^-]=0.75 mol/L;

d)soluble

CuCl₂ --> Cu²⁺+2Cl^-;

[Cu²⁺]=0.75 mol/L;

[Cl^-]= 1.5 mol/L;

e)soluble

NaCH3COO -->Na⁺+CH3COO^-;

[CH3COO^-]=[Na⁺]=0.75 mol/L;

f)insoluble

g)insoluble

h)insoluble
