Can any one please explain me why the answer to the following question is A and if my concept is right or wrong? 😔😔
- An aqueous solution of ethanoic acid is gradually diluted. Which of the following statements is *incorrect*?
A- the pH decreases
B- the value of Ka is unchanged
C- the concentration of ethanoic acid molecules decreases
D- the proportion of ethanoic acid molecules which dissociates increases
Now what I understood was..that as water is added to ethanoic acid, the dissociation of the acid increases hence the equilibrium shifts to right producing more of Hydrogen ions and this would cause pH to decrease..
But apparently that's not the case.😰
CH3COOH + H20 <---> CH3COO- + H+
(The equation is not given in question, i wrote it myself)
