Question

Question 8.
When potassium lodide solution is added to a solution of lead nitrate in test tube, a precipitate is
formed.
State the colour precipitate
ii) Name the compound precipitated
iii) Write balanced equation for chemical reaction
i) state the colour precipitate​

Answer 1

Explanation:

i) Brownish yellow (colour)

(ii)    Lead iodide(compound precipitate)

(iii)    Pb(NO3)2 + 2KI → PbI2 + 2KNO3(equation formed)

(iv)    Double displacement reaction.

Answer 2

Explanation:

a) yellow

b) Silver iodide

c)The colour of this precipitate formed is yellow

The compound precipitated is lead iodide

Chemical reaction:

KI+Pb(NO3)2-----------》Pb(I)2+KNO3

d) double displacement and precipitation
