A neutral solution means we are having equal amount of H⁺ and OH⁻. As we know,
Kw = [H⁺] [OH⁻] ------ (1)
So, in order to calculate Kw we first need to calculate [H⁺] and [OH⁻],
As, pH = -log [H⁺]
Or,
[H⁺] = 10⁻ˣ ∴ x = pH = 7.61
Putting value, and solving
[H⁺] = 2.45 × 10⁻⁸
As, our system is neutral, so concentration of [OH⁻] is exactly equal to concentration of [H⁺]. Now, putting values of [H⁺] and [OH⁻] in equation 1.
Kw = [2.45 × 10⁻⁸] [2.45 × 10⁻⁸]
Kw = 6.00 × 10⁻¹⁶
I believe it is balanced forces!
Answer:
temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above.The Earth's magnetic field is generated by the outer core.
