The image above shows what happens when hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed with water. Which statemen
t below is true about both solutions?
A. Both solutions contain solutes that do not dissolve completely in water.
B. Both solutions are saturated because they contain the maximum concentration of a solute dissolved in the solvent.
C. Both solutions will conduct an electric current because they both contain ions that can carry a charge.
D. Both solutions are acidic because they both contain hydrogen.

<h3>Further explanation</h3>mol C (MW=12 g/mol)
mol H(MW=1 g/mol) :
mol F(MW=19 g/mol)
mol ratio of C : H : O =1.52 : 0.51 : 0.89=3 : 1 : 1.75=12 : 4 : 7
Empirical formula : C₁₂H₄F₇
(Empirical formula)n=molecular formula
( C₁₂H₄F₇)n=562 g/mol
(12.12+4.1+7.19)n=562
(281)n=562⇒ n =2
