13. Determine if each salt will form a solution that is acidic, basic, neutral, or indeterminate. a. FeCls b. NaF c. CaBr2 d. NH4Br e. NH cIo f. Al(NO3)s B. C2HsNH3NOa h. K2CO3 i. Rbl

Solution

a) FeCl₃ is an acid salt because in solution it dissociates into Fe(OH)₃ is weak base and HCl a strong acid.

b). NaF is basic as it is the salt of a strong base, NaOH, and a weak acid, HF.

c). CaBr₂ is neutral

d)  NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt it is acidic

e)NH4ClO will dissociate in solution to form NH4+ and ClO- ions.Considering Kb is larger than Ka, therefore solution will be basic.

f) Aluminium nitrate is formed by the reaction of nitric acid(HNO3) and aluminium oxide (Al2O3). So, It is an acidic salt.

g) C₂H₅NH₃NO₃ is a salt of C₂H₅NH₃OH a weak base and nitric acid, a strong acid. It is an acidic salt

h) K₂CO₃ is a basic salt from a strong base KOH and weak acid H₂CO₃.

i) RbI  solution is neutral.

j)C₆H₄NH₃NO₃ is an acidic salt . As it is a salt of C₆H₄NH₃OH a weak base and nitric acid, a strong acid.
