Hello!
The dissociation reaction for Benzoic Acid is the following:
C₆H₅COOH + H₂O ⇄ C₆H₅COO⁻ + H₃O⁺
The Ka expression is the following and we clear for the concentration of H₃O⁺(X) assuming that the dissociation is little so we can rule it out in the denominator of the equation:
So, the pH of this Benzoic Acid solution is
2,29Have a nice day!
Answer:
Yes
Explanation:
Scientific laws must always be accompanied by theories. Without theories, laws cannot be formed. In other words, scientific laws are made from scientific theories.
<em>When a hypothesis has been tested by several independent researchers and found to be true, this leads to the development of a theory. A theory becomes a law when it is able to hold true against a wide range of similar phenomena.</em>
