take into consideration the reaction that $ceAgNO3$ and $ceHCl$. I read that silver chloride would certainly be formed. Yet $ceH > ceAg$ in reactivity, climate how can $ceAg$ displace $ceH$ indigenous $ceHCl$ ?

If there to be a reaction, $ceAgCl$ and also $ceHNO3$ to be to form. But then these would react again to give us the original compounds back. The actual question was to create down the reaction in between $ceAgNO3$ and $ceHCl$. Ns (wrongly) realized that the compound wouldn"t react because of the factors stated.

One that the most challenging parts the gimpppa.org is learning to acknowledge a kind of reaction based exclusively on its reactants. This has to be done prior to you can apply a reaction pattern to the problem, and also so that is vital to gain this step right in the beginning.

In this case, you are looking in ~ the reaction:

$$ceAgNO3 + HCl -> AgCl + HNO3$$

You already know the products, but are questioning just how these commodities can be formed due to the fact that the task of H is better than Ag, implying the Ag is less complicated to oxidize 보다 H. This is true - however take a look in ~ the oxidation numbers of each species in this reaction:

$ceAg: +1 -> +1$

$ceNO3: -1 -> -1$

$ceH: +1 -> +1$

$ceCl: -1 -> -1$

Since there is no as whole transfer the electrons, this can"t it is in a redox reaction, and that method activities won"t matter here.

That method there need to be an additional driving force for this reaction - one more reaction pattern that fits better.

I don"t want to give you the prize directly, but I will give you part advice that have to help:

Write the full equation - including the phases.

$$ceAgNO3(aq) + HCl(aq) -> AgCl(s) + HNO3(aq)$$

See if you deserve to find another reaction pattern that fits this equation better. Later, I"ll update this answer to display how you have the right to identify the exactly pattern for aqueous reactions using just the reactants.


As i mentioned, among the hardest parts of gimpppa.org is discovering to determine reaction fads based only on the reactants. This is a double-displacement (or metathesis, or precipitation) reaction. That is basic to watch now, given that the reactants room aqueous and also at least one of the assets is solid (the precipitate). Formation of the solid is the driving pressure for this reaction - the fast explanation is the the pressures attracting silver and also chloride ion together are stronger 보다 the solvation forces in between those ions and also water, as well as the pressures holding them to sodium and nitrate ions.

This is good, but how execute we predict the this is a precipitation reaction front of time?

The crucial is to have a great understanding of the 3 common varieties of salt/acid/base reaction that occur in aqueous solution, and to learn to recognize hints in the reactants.

Briefly, the three types that space most typically seen are:

PrecipitationAcid/base (Arrhenius definition)Redox (single displacement)

You deserve to recognize every of this by the reaction if you know what to look for.

Precipitation - 2 soluble salt (ionic compounds), or a salt through an acid or base.

Acid/base - one Arrhenius mountain and base (compound containing hydroxide)

Redox - a salt or acid and an element metal

There are plenty of other varieties of reactions that take place in aqueous solution, and many sports of the acid/base and also redox category, however these 3 cover the situations most typically seen in a classroom.

Once you have identified the most likely pattern that the reaction will follow, the following step is come predict the assets using that pattern to view if they do sense. If castle do, then you have actually likely liked correctly.

You have the right to use this algorithm for much more advanced gimpppa.org also - in organic gimpppa.org, for example, one of the major goals is to learn to guess reactions based upon functional groups. When you can identify useful groups and also have memorized reaction fads for them, the becomes possible to suspect a huge selection of reactions.
