Answer:
The pH of the solution is 5.31.
Explanation:
Let " is the dissociation of weak acid - HCN.
The dissociation reaction of HCN is as follows.
Initial C 0 0
Equilibrium c(1- ) c
c
Dissociation constant =
In this case weak acids is very small so, (1-
) is taken as 1.
From the given the concentration = 0.050 M
Substitute the given value.
Therefore, The pH of the solution is 5.31.
Answer:
See explanation and image attached
Explanation:
The reaction of bromine molecule with an alkene passes through a bridged intermediate known as the brominium ion.
It is a cyclic intermediate that contains a positively charged bromine ion as i have shown in the image attached.
The brominium ion is first formed during the bromininaton of alkenes.
