Which represents the self-ionization of water at 25°C? H2O + H2O 2H2 + O2 H2O + H2O H2O2 + H2 H2O + H2O 4H+ + 2O2- H2O + H2O H3O
+ + OH-
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
When molecules of same substance combine together to result in the formation of ions then this type of reaction is known as self-ionization.
For example, 
So, here two molecules of water are combining and they result in the formation of hydronium ion (
) and hydroxide ion (
).
Hence, this reaction is a self-ionization reaction.
The fourth answer is correct
H20 + H20 H30 + 0H-

Answer: The pH of a 4.4 M solution of boric acid is 4.3
Explanation:
at t=0 cM 0 0
at eqm
So dissociation constant will be:
Give c= 4.4 M and
= ?
Putting in the values we get:
