Question

the ions formed when sr(c₂h₃o₂)₂ dissociates in water are answer: a sr²⁺, c⁴⁻, h⁺, and o²⁻ b sr⁺ and c₂ho₂²⁻ c sr²⁺ and c₂h₃o₂⁻ d sr²⁺ and c₂ho₂²⁻ e no ions form as sr(c₂h₃o₂)₂ does not dissociate.

Explanation:

Step1: Identify cation and anion

Strontium acetate ($Sr(C_2H_3O_2)_2$) is an ionic compound. Strontium ($Sr$) is a Group - 2 element and forms a $Sr^{2 + }$ cation. The acetate ion is $C_2H_3O_2^-$.

Step2: Write dissociation equation

The dissociation of $Sr(C_2H_3O_2)_2$ in water is given by the equation $Sr(C_2H_3O_2)_2(s)
ightarrow Sr^{2 + }(aq)+2C_2H_3O_2^-(aq)$.

Answer:

C. $Sr^{2 + }$ and $C_2H_3O_2^-$
