Answer:
Sulfuric acid
Explanation:
Sulfuric acid is stronger than ethanoic acid because H+ ions or proton totally ionise in sulfuric acid (H2SO4) whereas in ethanoic acid (CH3COOH) H+ ion partially ionises. The resultant anion of sulfuric acid (HSO4-) is more stable than anion of ethanoic acid (CH3COO-).
So, ethanoic acid is a weak electrolyte and is less stronger than sulfuric acid.
Hence, the correct answer is sulfuric acid.
