Question

Нитрат серебра реагирует со всеми веществами набора а)KOH,HF,K2CO3 б)Hg,HCl,BaCl2 в)Cu,HBr,NaOH г)Au,Fe,K2SiO3

Answer 1

А) 2KOH + 2AgNO3 = Ag2O↓ + 2KNO3 + H2O
    HF + AgNO3 = AgF↓ + HNO3
    BaCl2 + 2AgNO3 = 2AgCl↓ + Ba(NO3)2
    
в) Cu + 2AgNO3 = 2Ag↓ + Cu(NO3)2
    HBr + AgNO3 = AgBr↓ + HNO3
    2NaOH + 2AgNO3 = Ag2O↓ + 2NaNO3 + H2O

Answer 2
