The pH of the solution of the given acid is 3.099
Let HX be the weak acid:
HX ⇌ +
For which:
= [
][
] / [HX]
If lies in the range
we can assume that the equilibrium concentrations used in the expression are a good enough approximation to the initial concentrations.
Rearranging and taking negative logs of both sides gives:
pH =
a is the concentration of the acid.
= -log (2×
) = 5.69
pH =
pH = 3.099

It represents a decomposition reaction because one reactant breaks apart and forms two products.
Explanation:
The type of chemical reaction depicted by Jane represents a decomposition reaction because on reactant breaks apart and forms two products.
In this reaction XY breaks apart to form X and Y. This is a decomposition reaction.
XY → X + Y
- Decomposition or cracking is the formation of two or more products from a single reactant.
- The break down of a compound into individual atoms or molecules falls into this category.
- The extreme instability of a compound drives such a reaction.
- The products is usually stable or it can dissociate further till it is stable.
