Answer:
The correct options are:
B. The HCl is the solute.
D. The H₂O is the solvent.
E. This mixture conducts electricity.
Explanation:
For the preparation of the HCl solution, 10 mL of HCl and 40 mL of water were mixed.
The compound that is present in the solution in a smaller ratio is the <u><em>solute</em></u> and the other compount -present in higher ratio- is the <u><em>solvent</em></u>.
So, the solute is HCl and the solvent is water (H₂O). Furthermore, water is considered as an universal solvent (for most of the polar and ionic compounds). According to this, the following options are correct:
B. The HCl is the solute.
D. The H₂O is the solvent.
Then, a condition for a solution that is able to conduct electricity is the presence of ions in the solution. When HCl is dissolved in water, it dissociates in ions according to the following equilibrium:
HCl ⇔ H⁺ + Cl⁻
The ions H⁺ and Cl⁻ are electrically charged so the solution can conduct electricity. According to this, the following option is also correct:
E. This mixture conducts electricity.
