Question
A 0.2 M solution of nitrous acid was produced in the laboratory (Ka = 4.0e-4).
What are the five statements that apply to the given problem above?
the ten statements where you can choose at are as follows;
1. The hydronium ion concentration at equilibrium is 8e-5 M.
2. The ionization extent of the acid is 4.5%.
3. The initial concentration of the acid is 0 M.
4. The change in concentration of the acid is represented by (0.2 - x) M.
5. 95.5% of the acid's concentration is the change in the concentration of the hydronium ion.
6. The hydronium ion concentration at equilibrium is 8.9e-3 M.
7. The pH of the solution is 4.1.
8. Insufficient data to proceed with the computation.
9. The equilibrium concentration of the acid is 0.2 M.
10. The "-x" in this case is not to be disregarded.
