At 100^ C the K _w of water is 55 times its value at 25^ C . What will be the pH of neutral solution? ( 55=1.74)

Options

  1. A7.00
  2. B7.87
  3. C5.13
  4. D6.13

Correct answer

D. 6.13

Step-by-step solution

aligned H ⁺ & = 55 10⁻¹⁴ pH & =- [ H ⁺ ] pH & =- [ 55 10⁻¹⁴ ] & = 1 2 [- (55 10⁻¹⁴ ) ] & =6.13 aligned
