Answer 1

Answer #1

1)

P^H = - log [H⁺]

given P^H = 7.4 there fore

[H⁺] = 10^-PH = 10^-(7.4) = 3.98x10^-8

[H⁺] = 3.98x10^-8

2)

P^OH = 14 - P^H

P^OH = 14 - 7.4 = 6.6

P^OH = - log [OH^-]

[OH^-] = 10^-POH = 10^-(7.4) = 2.51 x 10^-7

[OH^-] = 2.51 x 10^-7

3)

In the scale of PH 0 to 14

PH is 7 is nuetral

less than 7 it is acid

more than 7 it is basic

so give PH is 7.4 so that is basic (alkaline)
