• In weak electrolytes, an equilibrium is established between the ions and nonionized molecules.

• The non-electrolytes are those which do not ionize and exist as molecules in aqueous solutions.

• Arrhenius theory is applicable only to aqueous solutions.

• Degree of dissociation of a weak acid is directly proportional to the square root of its concentration.

Answer 1

Degree of dissociation of a weak acid is directly proportional to the square root of its concentration.

Explanation:

A weak acid's degree of dissociation (α) is inversely related to its concentration squared.

α = `sqrt("K"_"a"/"c")`
