Consider the following 1.0 mol L\(^{-1}\) solutions. Which one of the following lists the solutions in decreasing order (that is, strongest to weakest) of electrolyte strength?
A. Sodium phosphate > sulfuric acid > phosphoric acid > sucrose (sugar)
B. Sucrose (sugar) > sulfuric acid > phosphoric acid > sodium phosphate
C. Sulfuric acid > sodium phosphate > phosphoric acid > sucrose (sugar)
D. Sodium phosphate > phosphoric acid > sulfuric acid > sucrose (sugar)
Answer (3)
(a) sodium phosphate > sulfuric acid > phosphoric acid > sucrose (sugar) (b) sucrose (sugar) > sulfuric acid > phosphoric acid > sodium phosphate (c) sulfuric acid > sodium phosphate > phosphoric acid > sucrose (sugar) (d) sodium phosphate > phosphoric acid > sulfuric acid > sucrose (sugar)
The correct order of electrolyte strength (from strongest to weakest) is sulfuric acid > sodium phosphate > phosphoric acid > sucrose (sugar) due to their differing abilities to produce ions when dissolved in a solution. ;
The order of electrolyte strength from strongest to weakest is Sodium Phosphate > Sulfuric Acid > Phosphoric Acid > Sucrose. Thus, the correct answer is A. Sodium phosphate > sulfuric acid > phosphoric acid > sucrose (sugar).
