Why does HCl act as a weak base in HF solvent, even though it is a stronger acid compared to HF?
I've read that $\ce{HCl}$ acts as a weak base in $\ce{HF}$ solvent, which means $\ce{HCl}$ is supposed to lose $\ce{H+}$ ion to $\ce{HF}$. $\ce{HF}$ is a weak acid compared to $\ce{HCl}$, then shouldn'...

Stability of F- Cl- Br- I-? In aqueous state [closed]
If we talk about hydrolysis F- will be more heavily hydrolysed so it should be more stable in aqueous state.
But I know that HI is a stronger acid than HF. So the stability of conjugate acid ie I- ...

Why HCl is used in Lucas test?
In Lucas test $\ce{HCl}$ is used for acid-base reaction between $\ce{Zn(OH)Cl}$ to give $\ce{ZnCl2}$ and $\ce{H2O}$ which is kind of good because $\ce{ZnCl2}$ is formed again and used in first step ...

Lewis acidity comparison of boron and aluminium trichlorides
Lewis acidity is a function of electron deficiency on the acceptor atom, which in this case is $\ce{B}$ and $\ce{Al}$ respectively.
Back donation is better as is the case of $\ce{B}$, due to better ...

Order of basicity of halides [duplicate]
The order of basicity of halides is $\ce{F- >Cl- > Br- > I-}$
My teacher explained this on the basis that the smaller is the ion, the greater is the charge/size ratio, hence it more ...
