Explanation:
if it is on the periodic table it is an element
Answer:
2.9 is the initial pH of the analyte solution.
Explanation:
The dissociation constant of acetic acid as per theoretical value = 

The initial concentration of acetic acid = c = 0.0900 M

initially
c 0 0
At equilibrium
(c-x) x x
The expression of dissociation constant :
![K_a=\frac{[Ac^-][H^+]}{[HAc]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BAc%5E-%5D%5BH%5E%2B%5D%7D%7B%5BHAc%5D%7D)


Solving for x:
x = 0.001264 M
![[H^+]=0.001264 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.001264%20M)
The pH of the solution :
![pH=-\log[0.001264]=2.898\approx 2.9](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B0.001264%5D%3D2.898%5Capprox%202.9)
2.9 is the initial pH of the analyte solution.
