✔ 最佳答案
Add acidified silver nitrate solution into two acid,White precipitate formed in dilute hydrochloric acid.No precipitate formed in dilute sulphuric acid.
AgNO3(aq)+HCl(aq) ---＞AgCl(s)+HNO3(aq)
2AgNO3(aq)+H2SO4(aq)---＞Ag2SO4(s)+2HNO3(aq)
But Ag2SO4(s) can redissolve in AgNO3,because it is acidified,which contain acid.
