Answer 1

pH 3 = 10 times of pH 4 in terms of H⁺ concentration

Further explanation

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ion. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.

So pH 3 and pH 4 have a difference in the concentration of H⁺ ion of 10¹ = 10

pH 3 = -log[10⁻³]

pH 4 = - log[10⁻⁴]

pH 3 = 10 times of pH 4 in terms of H⁺ concentration

And pH 3 is stronger in acid than pH 4
