Why is NO3 always a spectator ion?
If we compare the solutions before and after the reaction, sodium and nitrate ions are present in both solutions. They do not undergo any chemical change at all. These ions are called spectator ions since they don’t participate in the chemical reaction at all (they just “watch”).
Is NO3 a strong conjugate base?
A) NO3− A strong acid will dissociate to form a weak conjugate base and the weak acid will dissociate to form a strong conjugate base. …
Why is NO3 not basic?
The species NO3- is the conjugate base of the strong acid, HNO3. Again, the dissociation of HNO3 in water goes to completion, and NO3- will not accept a proton. It has no basic activity.
Why the conjugate base of a strong acid is a weak base?
A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl– to reaccept a proton. Consequently, Cl– is a very weak base. A strong base like the H– ion accepts a proton and holds it so firmly that there is no tendency for the conjugate acid H2 to donate a proton.
Is nh4+ Always a spectator ion?
To answer this, we will refer to the solubility rules in order to determine if the ions will form an insoluble salt (precipitate) or not. Therefore, the ions that will always be a spectator ion in a precipitation reaction are (b) NO3– and (c) NH4+.
Is NO3 a spectator ion?
The sodium ion has remained a spectator ion and the nitrate ion, NO3-, is also a spectator ion. While spectator ions remain unchanged in solution and don’t take part in the chemical reaction, they serve as a means of delivery for the materials required for the reaction.
What makes a strong conjugate base?
There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): ⚛ The stronger the acid, the weaker its conjugate base. ⚛ The weaker the acid, the stronger its conjugate base. ⚛ The weaker the base, the stronger its conjugate acid.
Is NO3 a strong acid?
Nitric acid is a stronger acid than nitrous acid because its conjugate base is more stable. The NO3- ion has excess negative charge spread out over 3 oxygen atoms while the excess negative charge in NO2- is spread out over on 2 oxygen atoms.
Why is conjugate base strong?
So, the conjugate Bronsted-Lowry base that forms weakly wants to accept a proton. That makes it a weak (Bronsted-Lowry) base. Weak bases have a strong tendency to get H+ and/or donate an electron pair. Strong bases have a weak tendency to get H+ and/or donate an electron pair.
