✔ 最佳答案
pH = 3 = 10^-3 = 0.001 pH = 6 = 10^-6 = 0.000001
0.000001 x 1000 = 0.001
Hence answer 'e' 1000.

pH = -log[H⁺]
Then, [H⁺] = 10^(-pH)
[H⁺] at pH 3 = 10⁻³ M
[H⁺] at pH 6 = 10⁻⁶ M
([H⁺] at pH 3) / ([H⁺] at pH 6) = 10⁻³/10⁻⁶ = 1000
Answer: e. 1000
Then, [H⁺] = 10^(-pH)
[H⁺] at pH 3 = 10⁻³ M
[H⁺] at pH 6 = 10⁻⁶ M
([H⁺] at pH 3) / ([H⁺] at pH 6) = 10⁻³/10⁻⁶ = 1000
Answer: e. 1000
