By definition, Bronsted-Lowry acid is a proton donor in the acid-base neutralization reaction. When a weak acid like acetylsalicylic acid is reacted with water, the water here acts as the Bronsted-Lowry base. This is possible because water has properties of amphoterism - can act as an acid or base. In this case, acetylsalicylic acid would have to donate its H+ atom to water, so that it would yield a hydronium ion, H₃O⁺. The complete net ionic reaction is shown in the picture.
So, in the reaction, the products yield are the acetylsalicylate ion and the hydronium ion.
So, in the reaction, the products yield are the acetylsalicylate ion and the hydronium ion.
Answer:
76.875 cm3
<h2>Explanation:</h2>Since: Density =
Then: Volume =
The mass of the box = 246g
and the density = 3.2 g/cm3
Then: The volume =
= 76.875 cm3
