Lead (II) nitrate reacts with potassium iodide to form lead
2015年12月28日 · The potassium ion is "K"^+ and the iodide ion is "I"^-. The two charges balance in a 1 : 1 ratio, so potassium iodide is simply "KI". In lead (II) iodide, the charges balance in a 1 : 2 ratio, so the formula is "PbI"_2. Finally, in potassium nitrate, the charges balance in another 1 : 1 ratio, giving a formula of "KNO"_3 .
