Question

I have a few mixture problems i could really use some help with. Thank you chegg family.

1.) The compound sodium sulfate is a strong electrolyte. Write the transformation that occurs when solid sodium sulfate dissolves in water.
Use the pull-down boxes to specify states such as (aq) or (s). _____ () => _____() + ______()

2.)The compound potassium nitrate is a strong electrolyte. Write the transformation that occurs when solid potassium nitrate dissolves in water.
Use the pull-down boxes to specify states such as (aq) or (s).   _______() => ______() + ______()  

3.)Classify each of the compounds as soluble (s) or not Soluble (ns):

Explanation / Answer

1. Sodium sulfate dissolve in water to gives sodium ion and sulfate ion

Na2SO4(s) ---------------> 2Na^+ (aq) + SO4^2- (aq)

2. potassium nitrate dissolve in water to gives potassium ion and nitrate ion

KNO3(s) ----------------->K^+ (aq) + NO3^- (aq)

3. All nitate salts are soluble in water. All sulfate salts are (expect alkali, NH4^+) insoluble in water. Except alkali, NH4+ salt all hydoxide salts are insoluble in water

   potassium nitrate soluble

    cobalt(II) hydroxide insoluble

   calcium sulfate insoluble

   magnesium iodide soluble

manganese(II) sulfide insoluble ( all sufide salts are insoluble in water)

potassium acetate soluble       

barium chloride soluble

cobalt(II) sulfate insoluble

zinc nitrate soluble
