Question

1. identify the solute(s) and solvent in each of the following solutions:

(a) salt water
(b) carbonated water
(c) a 3 % aqueous solution of hydrogen peroxide

Explanation:

• For a solution, the solute is the substance that is dissolved and the solvent is the substance in which the solute is dissolved. In most cases, the solvent is present in a larger amount.
• In salt - water, salt (\(NaCl\)) is dissolved in water.
• In carbonated water, carbon dioxide (\(CO_2\)) is dissolved in water.
• In a \(3\%\) aqueous solution of hydrogen peroxide (\(H_2O_2\)), hydrogen peroxide is the solute and water is the solvent (since it is an aqueous solution, water is the main component).

Answer:

(a) Solute: salt (\(NaCl\)); Solvent: water (\(H_2O\))
(b) Solute: carbon dioxide (\(CO_2\)); Solvent: water (\(H_2O\))
(c) Solute: hydrogen peroxide (\(H_2O_2\)); Solvent: water (\(H_2O\))
