Calculate the % dissociation of 0.10 M solution of acetic acid (pKa = 4.75)
madreJ [45]

Given :

Molarity of acetic acid solution, M = 0.10 M.

pKa of acetic acid, pKa = 4.75 .

To Find :

Percentage dissociation of 0.10 M solution of acetic acid.

Solution :

We know, pK_a = -log\  K_a

Taking antilog both side, we get :

K_a = 1.78\times 10^{-5}

Since, acetic acid has 1 hydrogen atom to loose , so it is a monoprotic acid.

Now, percentage dissociation of monoprotic acid is given by :

\alpha = \sqrt{\dfrac{K_a}{C}}\\\\\alpha =\sqrt{ \dfrac{1.78\times 10^{-5}}{0.1}}\\\\\alpha =  0.0133\times 100 = 1.33 \%

Hence, this is the required solution.

1. How does a star's life begin?
Phantasy [73]

Answer:

A star begins its life as a cloud of dust and gas (mainly hydrogen) known as a nebula. A protostar is formed when gravity causes the dust and gas of a nebula to clump together in a process called accretion. ... If a critical temperature in the core of a protostar is reached, then nuclear fusion begins and a star is born.
