Question

2. Determine which of the following are STRONG, WEAK or NONELECTROLYTE A. OF4 B. Ba(MnO4) C. S20s D. HI(aq) E. Mg(OH):(aq) F. H CO:(aq) G. AI(NO:)s H. (NH)sPO I. CHi6 J. KI

Answer 1

1) OF4--------doe snot exist

2) Ba(MnO4)2----------------May be non eletcrolyte or week electrolyte(Since the eletronegative difference is considerably less between Ba and Mn)

3) S2O5---------------------Non electrolyte for the same reason mentioned above

4) HI------------------Strong electrolyte (Ionic compound)

5) Mg(OH)2aq------------------------Strong electrolyte (Ionic compound)

6) H2C2O2 (aq) ------------------------------- weel electrolyte

7) Al(NO2)3---------------------------Strong electrolyte

8) (NH4 )3(PO4)--------------------------- Week electrolyte

9) C7H16------------------------non electrolyte

10) KI----------------------Strong elctrolyte
