Question

Which of the following do not follow ostwald dilution law
1) CH3COOH 2). HNO3
3) HCl. 4) H2SO4

Answer 1

Answer:

HCL do not follow the ostwqld dilution law

Answer 2

CH3COOH only follows the Ostwald dilution law and HNO3, HCl and H2SO4 are not follows the Ostwald dilution law.

Explanation:

Ostwald's dilution law : "The degree of dissociation weak electrolyte is inversely proportional to the square root of the concentration".

• It is understood from the law, that the Ostwald's dilution law is applicable only for weak electrolytes.

                                   $\alpha = \sqrt{\frac{K_{a}}{c}}$      

• The strong electrolytes can completely dissociated so their value of K becomes infinity when the dissociation extent become less than 1 or zero.
• In case of weak electrolytes, the dissociation externt is small when compared to strong electrolytes, so we can substitute the values and find further.  
• CH3COOH - weak electrolyte
• HNO3- Strong electrolyte
• HCl - Strong electrolyte (strong acid)
• H2SO4 - Strong acid

Therefore, from the given list CH3COOH only follows the Ostwald dilution law and HNO3, HCl and H2SO4 are not follows the Ostwald dilution law.
