Answer:

The vinegar is highly acidic by 100 times than yogurt.

Explanation:

∵ pH = -log[H⁺]

  • The concentration of H⁺ in yogurt:

∵ pH = -log[H⁺]

∴ 5 =  -log[H⁺]

∴  [H⁺] = 1.0 x 10⁻⁵ M.

  • The concentration of H⁺ in vinegar:

∵ pH = -log[H⁺]

∴ 3 =  -log[H⁺]

∴  [H⁺] = 1.0 x 10⁻³ M.

the ratio of H⁺ in vinegar to that in yogurt = 1.0 x 10⁻³ M / 1.0 x 10⁻⁵ M = 100.0.

<em>∴ The vinegar is highly acidic by 100 times than yogurt.</em>
