Which of the substances can dissociate? a) 40% aqueous solution of sulfuric acid b) solution of sugar in water

Which of the substances can dissociate? a) 40% aqueous solution of sulfuric acid b) solution of sugar in water c) anhydrous sulfuric acid d) aqueous solution of hydrogen chloride

Electrolytic dissociation is the process of decay of an electrolyte substance into ions in a solution. Developed the theory of Svante Arrhenius.

Let’s analyze the given Iv-va:

1. Sulfuric acid is a strong electrolyte; it exists in the solution in the form of ions:

H2SO4 = 2H + + SO42-.

2. Sugar is the common name for sucrose (a disaccharide consisting of glucose and fructose). Carbohydrates (like many other organic substances) are not electrolytes. in solutions exist in the form of molecules.

3. Anhydrous sulfuric acid also exists in the form of molecules due to the absence of an aqueous medium, but its reactivity remains high (this mechanism is explained by the Bronsted-Lowry theory).

4. Hydrogen chloride (hydrochloric acid) is a strong electrolyte, in an aqueous solution exists in the form of ions:

HCI = H + + CI-.

Answer: a), d).
