consider the given case as first anions will

Question

Consider the given case as first anions  will not precipitate in the presence of AgNO₃ and second anions get precipitated in the presence of AgNO₃ and precipitates (the resulting) will liquefy upon acidification with HNO₃  in third case you find that Anions and AgNO₃ presence form precipitate but  it will not dissolve upon acidification. Now answer the given questions after considering these cases 

1)Write down  a net ionic equation  for any reaction that forms a precipitate

2)discover the anions that make gas upon adding of hydrochloric acid

3). recognize the anions that not precipitate with AgNO₃. 40 make out the anions that react with AgNO₃ to form precipitates that liquefy when acidified with HNO₃. E. name the anions that react with AgNO₃  to form precipitates that do not dissolve when acidified with HNO₃
