PH scale, PH of strong acids and strong bases

Question

Among the following
a) On dilution, the pH of an acid increases
b) A solution with pH = 5 is 100 times more basic than a solution with pH = 3
c) A solution with pH = 8 is 1000 times more acidic than a solution with pH = 11
d) The pH of 10^-9M KOH is slightly greater than 7

Moderate

A

all are correct
B

a,d are only correct
C

a,b,c are only correct
D

all are wrong

Solution

a) A decrease in the concentration of H⁺ increases the P^H value.
b) A unit distance in P^H scale is equivalent to a factor of 10.
d) Since the concentration of KOH is less than 10^-6 M, we will have to consider the OH^- ions furnished from water and proceed to calculate the final P^H.
