Question

Помогите пожалуйста. SnCl2 +AgNO3=? AlCl3+KOH(надлышок)=?

Answer 1

SnCl2 + 2AgNO3 = Sn(NO3)2 + 2AgCl
AlCl3 + 3KOH = Al(OH)3 + 3KCl

Answer 2

Reactions of SnCl2 and AgNO3

The reaction between SnCl2 (tin(II) chloride) and AgNO3 (silver nitrate) results in the formation of a white precipitate of silver chloride (AgCl) and the formation of Sn(NO3)2 (tin(II) nitrate) in solution.

The balanced chemical equation for this reaction is:

SnCl2 + 2AgNO3 → Sn(NO3)2 + 2AgCl

Reactions of AlCl3 and KOH

When aluminum chloride (AlCl3) reacts with potassium hydroxide (KOH) in excess, it forms a complex ion called hexahydroxyaluminate(III) ion, [Al(OH)6]3-. The balanced chemical equation for this reaction is:

AlCl3 + 3KOH → K[Al(OH)4] + 2KCl

This reaction is a classic example of a Lewis acid-base reaction, where AlCl3 acts as a Lewis acid and KOH acts as a Lewis base.
