Question

Among the following
a) pH of water decreases with increases in temperature
b) pH of water decreases by the addition of base
c) pH of water increases by the addition of acid
d) At any temperature pH of water is equal to $\frac{p^{K_{w}}}{2}$

Easy

A

all are correct
B

b, c and d are correct
C

a and d are correct
D

a,b and c are correct

Solution

As temperature increases, P^H scale contracts.
P^H of water increases by the addition of base.
P^H of water decreases by the addition of acid.
At any temperatrue, P^H of water is equal to $\frac{p^{K_{w}}}{2}$
