Question

based on the chemical formula provided, classify each compound as a strong, weak, or non - electrolyte.
a. $nac_2h_3o_2$ select an answer
b. $hno_2$ select an answer
c. $ccl_4$
d. $co_2$
e. $mg(c_2h_3o_2)_2$
f. $hcn$
g. $au(clo)_2$ select an answer
h. $na_2s$ select an answer
(options: strong electrolyte, weak electrolyte, nonelectrolyte)

Explanation:

• A. \( \boldsymbol{NaC_2H_3O_2} \): Sodium acetate is a salt of a strong base (NaOH) and a weak acid (acetic acid). Salts of strong bases and weak acids are strong electrolytes as they dissociate completely in solution.
• B. \( \boldsymbol{HNO_2} \): Nitrous acid is a weak acid. Weak acids only partially ionize in solution, so it is a weak electrolyte.
• C. \( \boldsymbol{CCl_4} \): Carbon tetrachloride is a covalent compound and does not dissociate into ions in solution. It is a nonelectrolyte.
• D. \( \boldsymbol{CO_2} \): Carbon dioxide is a nonmetal oxide. It reacts with water to form carbonic acid, but the compound itself does not dissociate into ions. It is a nonelectrolyte.
• E. \( \boldsymbol{Mg(C_2H_3O_2)_2} \): Magnesium acetate is a salt of a strong base (Mg(OH)₂) and a weak acid (acetic acid). Salts of strong bases and weak acids dissociate completely, so it is a strong electrolyte.
• F. \( \boldsymbol{HCN} \): Hydrocyanic acid is a weak acid. Weak acids partially ionize, so it is a weak electrolyte.
• G. \( \boldsymbol{Au(ClO)_2} \): Gold(II) hypochlorite is a salt. Salts (especially those of metals and polyatomic ions) are strong electrolytes as they dissociate completely in solution.
• H. \( \boldsymbol{Na_2S} \): Sodium sulfide is a salt of a strong base (NaOH) and a weak acid (H₂S). Salts of strong bases and weak acids dissociate completely, so it is a strong electrolyte.

Answer:

A. Strong Electrolyte
B. Weak Electrolyte
C. Nonelectrolyte
D. Nonelectrolyte
E. Strong Electrolyte
F. Weak Electrolyte
G. Strong Electrolyte
H. Strong Electrolyte
