Question

lead nitrate (s) is added to potassium iodide (s) a-does the reaction takes place. b-what should be done so that the reaction takes place. C- what change is observed. D- name the type of reaction​

Answer 1

Answer:

Explanation:a) Yes, Reaction will take place..

B)When you mix two chemicals, their particles may combine and make two new compounds. When you combine lead nitrate and potassium iodide solutions, a double-replacement reaction happens. The two compounds react, and the positive ions and negative ions of the two reactants switch places, creating two new compounds.

Answer 2

Answer:

Pb(NO3)2(aq)+2KI(aq)->PbI2(s)+2KNO3(aq)

(a)No the reaction won't takes place

(b)the two reactants lead nitrate(s) and potassium iodide(s) should be converted into molten or aqueous form.

(c) a yellow colored precipitate is formed

(d)it is a 'double displacement reaction'

Explanation:

(a)it is a double displacement reaction and know that in this type of reaction exchange of ions of the reactants takes place,but as it is given that lead nitrate and potassium iodide is in the solid state,and hence it won't get ionised and the reaction won't take place.

(b)firstly the reactants should me converted to aqueous or molten form by melting or diluting it, so that it get ionised and the reaction takes place.

(c)lead iodide (PbI2)forms a yellow colored precipitate as it is in the solid form.

(d)as in this reaction exchange of ions takes place ,hence it is double displacement reaction.
