Can a weak acid react to give a stronger acid? [closed]
I was trying to understand why $\ce{AgCl}$ does not dissolve in $\ce{HNO3}$ and the reaction I could think of was something like this:
$$\ce{AgCl + HNO3->AgNO3 + HCl}$$
I could not understand why ...

Why can't Grignard reagents react like Organolithium does (with acids)?
I'd read yesterday that Grignard reagents can't give ketones on reaction with carboxylic acids. It is because of the fact that Grignard reagent is a "super-base", and it will deprotonate the ...

Reaction of Silicon Dioxide with Hydrofluoric Acid [duplicate]
I learnt that $\ce{SiO2}$(Silicon dioxide) doesn't react with any acid except $\ce{HF}$. So what is special about $\ce{HF}$?
Why does only $\ce{HF}$ reacts with $\ce{SiO2}$ even though $\ce{HF}$ has a ...

What is the order of acidity for hydrogens in primary, secondary and tertiary alkanes, alkenes, and cycloalkanes [duplicate]
The bond dissociation energies of C-H bonds in alkanes, alkenes and aromatic compounds decrease in the following order: primary > secondary > tertiary > allylic > benzylic.
The weaker the bond, the ...
