Question

pH of a weakacid solution in 0.1 M solution is 4.3. What is the pH in 0.01 M solution​

Answer 1

Answer:10.6

Explanation:

Answer 2

Answer:

Explanation:

ph=4.3

h plus = 10^-4.3

=1/anti log 4.3

=1/10^4*2

=0.5*10^-4

=5*10^-5

c alpha = h plus

0.1 alpha = 5*10^-5

alpha= 5*10^-4

ph of same solution of 0.01 m

h plus= c alpha

=0.01*5*10^-4

=5*10^-6

ph= -log h plus

=6-log 5

=6-0.69

=5.31
