Answer:

A) Adding [tex]H_2SO_4[/tex]

B) Adding [tex]HI[/tex]

Explanation:

A) Adding [tex]H_2SO_4[/tex]

1) [tex]H_2SO_4 + 2 AgNO_3 \longrightarrow Ag_2SO_4 +2 HNO_3[/tex]

2) [tex]H_2SO_4 + Cu(NO_3)_2 \longrightarrow CuSO_4 +2 HNO_3[/tex]

[tex]CuSO_4[/tex] is very soluble in water and, in the other hand, [tex]Ag_2SO_4[/tex] is not.

B) Adding [tex]HI[/tex]

1) [tex]2 HI + MgCl_2 \longrightarrow MgI_2 + 2 HCl[/tex]

2) [tex]2 HI + CuCl_2 \longrightarrow CuI_2 + 2 HCl[/tex]

[tex]MgI_2 [/tex] is very soluble in water and, in the other hand, [tex]CuI_2[/tex] is not.

Answer:

HCl and H2S

HCl + AgNO3 ---> (HNO3) + AgCl.

Agcl is white in color and is formed by the reaction between colorless aqueous silver nitrateto a colorless solution solution of sodium chloride to produce an opaque white precipitate

H2S + CuCl2 ----- > CuS + HCl

CuS It is a moderate conductor of electricity. A black colloidal precipitate of CuS is formed when hydrogen sulfide, H2S, is bubbled through solutions of Cu(II) salts
