Answer 1

Answer:

hey !

all bases are alkali.. they are not different ..

no, i will not suggest to do that , as the marbles are CaCO3 which is basic in nature and vinegar and other juice stuff are acidic ,therefore these acids may react with the marble and this will spoil the marbles ..

hope it helps...
