Question

Write equations showing the ions present after the following strong electrolytes are dissolved in water.

a. HNO3 d. SrBr₂ g. NH₄NO₃

b. Na₂SO₄ e. KClO₄ h. CuSO₄

c. Al(NO₃)₂ f. NH₄NO₃ i. NaOH

Short answer

Strong electrolytes are completely dissociable in aqueous solution.

Step-by-step solution

Step1:Concept

Readily disassociate into cation and anion parts in aqueous solution.
