Answer 2

as we know Ammonium chloride sublimes on heating so we will heat the mixture and the ammonium chloride will sublime. Then salt and sand will be left we will add water to the mixture and salt dissolves and sand is left at bottom of container you can take the sand out using filtration process and the solution of water and salt will be left behind. This can be evaporated to obtain salt
