Answer:
No, no precipitate is formed.
Explanation:
Hello there!
In this case, since the reaction between silver nitrate and sodium acetate is:
[tex]AgNO_3(aq)+NaC_2H_3O_2(aq)\rightarrow AgC_2H_3O_2(s)+NaNO_3(aq)[/tex]
In such a way, we can calculate the concentration of silver and acetate ions in the solution as shown below, and considering that the final total volume is 50.00 mL or 0.0500 L:
[tex][Ag^+]=\frac{20.00mL*0.077M}{50.00mL}=0.0308M[/tex]
[tex][C_2H_3O_2^-]=\frac{30.00mL*0.043M}{50.00mL}=0.0258M[/tex]
In such a way, we can calculate the precipitation quotient by:
[tex]Q=[Ag^+][C_2H_3O_2^-]=0.0308*0.0258=7.95x10^{-4}[/tex]
Which is smaller than Ksp and meaning that the precipitation does not occur.
Regards!
