Polyunsaturated fatty acids contain more than one double bond in its hydrocarbon chain.
Hope this helps! Let me know if you have any questions.
Explanation:
The pH of a strong acid when titrated with a strong base is equal to 7 because of the formation of a neutral salt which corresponds to pH = 7.
But on the other hand,
The titration of the weak acid and strong base, the reaction taking place is:
HC₂H₃O₂ + OH⁻ ⇒ H₂O + C₂H₃O₂⁻
At the equivalence point, the pH is greater than 7 because of the conjugate base formed in the above reaction which gives OH⁻ in the solution as:
C₂H₃O₂⁻ + H₂O ⇒ HC₂H₃O₂ + OH⁻
<u>The hydroxide ions produced in the above reaction results in the pH above 7 (basic).</u>
