Electrolyte

What happens to a solution when free ions are released?

• It becomes less dense.

• It becomes electrically conductive.

• It changes color.

• It evaporates quickly.

What ions are formed when salt dissolves in water?

• Carbon and nitrogen ions

• Hydrogen and oxygen ions

• Potassium and calcium ions

• Chlorine and sodium ions

Why can salt solutions conduct electricity?

• Because they are solid

• Because they are colorless

• Because they have free-moving ions

• Because they contain sugar molecules

Why do sugar solutions not conduct electricity?

• Because sugar solutions are too thick

• Because sugar solutions are too sweet

• Because sugar is a solid

• Because sugar molecules do not split into ions

What is a key difference between salt and sugar solutions in terms of electrical conductivity?

• Salt solutions conduct electricity, while sugar solutions do not

• Salt solutions are sweeter than sugar solutions

• Salt solutions are thicker than sugar solutions

• Salt solutions are more colorful than sugar solutions
