Question

egg whites solidify in the presence of acids. would lemon juice (ph 2.3) or orange juice (ph 3.5) be better for solidifying egg whites? why? orange juice, because it donates fewer h+ ions than lemon juice. lemon juice, because it donates more h+ ions than orange juice. lemon juice, because it donates fewer h+ ions than orange juice. orange juice, because it donates more h+ ions than lemon juice.

Explanation:

The lower the pH, the more acidic a solution is and the higher the concentration of H⁺ ions. Lemon juice has a lower pH (2.3) than orange juice (3.5), so it is more acidic and donates more H⁺ ions. Since egg - whites solidify in the presence of acids, the more acidic lemon juice will be better for solidifying egg - whites.

Answer:

Lemon juice, because it donates more H⁺ ions than orange juice.
