Which of the following substances will form electrolytes and which will form molecular solutions when dissolved in water?

Question

1. Chromium (II) nitrate: Cr(NO3)2 
2. 1-propanone: CH3CH2CHO 
3. Trisodium citrate: Na3C6H5O7 
4. Ammonium chloride: NH4Cl  

Answer 1

Electrolytes will ionize or dissociate in solution. Molecular solutions will not ionize or dissociate in solution.

1. Chromium (II) nitrate: Cr(NO3)2 - electrolyte
2. 1-propanone: CH3CH2CHO - molecular
3. Trisodium citrate: Na3C6H5O7 - electrolyte
4. Ammonium chloride: NH4Cl  - electrolyte
