Solubility of SrF2 in aqueous solution of NaF
This might be really simple question but I have no idea how to proceed to solve such kind of question.
The solubility product of $\ce{SrF2}$ in water is $\pu{8E-10}$. Calculate its solubility in 0.1M ...

Is lead iodide a strong electrolyte?
So, lead iodide is insoluble. I see conflicting answers online. Some say it's a weak electrolyte because it is insoluble, others say it is a strong electrolyte because it is an ionic compound and any ...

What happens during a displacement reaction? [closed]
When Zn metal is added to a solution of Cu(II)SO4, Zinc displaces Cu to form ZnSO4 as Zn is more reactive than Cu. What I don't understand is how.
1- What I'm assuming is: Zn metal collides with [SO4]...

Would ionic conduction be halted by shielding at the electrodes?
I've done this experiment myself and seen it front of my eyes. Set up a basic circuit with a battery, an LED, and connect the circuit with a salt-water solution and copper wire. The LED lights up.
If ...

Dissociation behaviour of polyelectrolytes
Assuming a solution of 100 polycationic molecules, each of them carrying 100 amino groups and an apparent pKa of 6.5. Would it mean that, at a pH of 6.5,
50 molecules will be fully protonated
50 ...

How do you write the ionization equation for calcium hydroxide?
This is a base that would ionize completely, and the dissociation equation would look like this: $$\ce{Ca(OH)2 <--> Ca^2+ + 2OH-}$$ but how would I write the Brønsted equation with water? $$\ce{...

So, is baking soda actually a strong base? [duplicate]
Based on my recent thoughts, when baking soda ($\ce{NaHCO3}$) is dissolved in water, the following hydrolysis reaction occurs:
$$\ce{NaHCO3 + H2O <=> NaOH + H2CO3}$$
However,
$$\ce{H2CO3 -> ...

Why does the conductivity of a LiOH solution decrease when boric acid is added?
If I start with pure water and add $\ce{LiOH}$ the conductivity of solution increases. However, if I then dissolve boric acid in the same solution the conductivity falls. I would have thought adding ...

Crystallisation and crystal surface
It is my understanding that if you put table salt (as an example of polar compound) in water, the Na+ and Cl- ions will freely move through the solution. They will make the solution conductive and ...

Dielectric constant and dissolution of ionic salts
We say that salts like $\ce{NaCl}$ get easily dissolved in water because the dielectric constant of water is very high. I know the dielectric constant of water is 81 and if a salt is put into water ...

How do hydrogen bonds break the ionic bonds of a crystal lattice? [duplicate]
In the case of water dissolving sodium chloride. I was under the impression that hydrogen bonds were much weaker than the ionic bonds in sodium chloride, so how do they overcome the ionic bond ...

If I mix carbon dioxide and sodium hydroxide in the right amounts in water, do I get baking soda?
Suppose I need a sodium bicarbonate solution (for non-food related reasons). Can I get something resembling it by mixing $\ce{NaOH}$ and $\ce{CO2}$ in water?
Of course one should not attempt to make ...
