Kw at 25°C = 1 × 10–14 At 25ºC
Kw = [H+] [OH–] = 10–14 At 100°C (given) Kw = [H+] [OH–] = 55 × 10–14
∵ for a neutral solution [H+] = [OH–]
∴ [H+]2 = 55 × 10–14
or [H+] = (55 × 10–14)1/2
∵ pH = – log [H+]
On taking log on both side – log [H+] = –log (55 × 10–14)1/2
∵ for a neutral solution [H+] = [OH–]
∴ [H+]2 = 55 × 10–14
or [H+] = (55 × 10–14)1/2
∵ pH = – log [H+]
On taking log on both side – log [H+] = –log (55 × 10–14)1/2
pH = – 0.87 + 7
= 6.13
= 6.13
