Question

Complete the missing components / variables given as (x) & (y) in the following reactions.pb (NO3)+2Kl= Pbl2 (x)+2KNO3 (y)

​

Answer 1

Answer:

(a) Pb(NO3 )2 (aq) + 2KI (aq) ⇨ PbI2 (s) + 2KNO3 ... given as x and y in the following reactions (a) Pb(NO3) 2 (aq) + ...

Explanation:

Pb(NO

3

)

2

(aq)+2KI(aq)→PbI(s)+2KNO

3

(aq)

Above reaction is a precipitation and a double displacement reaction in which solid precipitates of lead iodide (PbI) are formed .Therefore x represents solid (s) form of lead iodide and y represents aqueous (aq) form of potassium nitrate.
