hello:)!! for the preparation of salts , I don’t really understand the part where acids react with insoluble bases. do I just memorise it? :) thanks!

I think if u will clear your topic it would be more helpful.

But if u r unable to do it, then u can just memorise it.

See, i will try to help u.

Salts are formed when acids react with bases.

and this reaction is called neutralisation reaction.

e.g. HCl+NaOH=NaCl+H2O.

It is very easy.

Other examples:

H2SO4+Mg(OH)2=MgSO4+2H2O.

There may be some other reactant with acid like u have mentioned above.

hope it helps u

plz mark as brainliest...
