Question

(1) what is observed when a solution of potassium iodide is added to a solution of lead nitrate taken in test tube(2) which type of reaction is this(3) write the balanced chemical equation reaction involved in the above

Answer 1

Answer:

In a double displacement reaction, two chemicals react, and the positive (cation) and negative (anion) ions of the two reactants exchange positions, producing two new compounds or products.

Explanation:

A yellowish solid precipitates when a solution of potassium iodide is added to a solution of lead nitrate that has been taken in a test tube. Lead iodide is thie yellowish solid. Lead iodide and potassium nitrate are produced together.

                              Pb(NO₃)₂ + 2KI → 2KNO₃ + PbI₂ (s)

In words,

    Lead nitrate + Potassium Iodide → Potassium Nitrate + Lead Iodide

It is known as the double displacement reaction. When elements of two compounds are interchanged between each other, the reaction is a double displacement reaction.

Hence, each answer is mentioned above.

Answer 2

Concept:-

The methodical process of organising knowledge about the cosmos into testable, comprehensible, and predictable hypotheses is known as science.

Given:-

Given that a question "$(1)$what is observed when a solution of potassium iodide is added to a solution of lead nitrate taken in test tube$(2)$ which type of reaction is this$(3)$ write the balanced chemical equation reaction involved in the above."

Find:-

We need to find that "$(1)$what is observed when a solution of potassium iodide is added to a solution of lead nitrate taken in test tube$(2)$ which type of reaction is this$(3)$ write the balanced chemical equation reaction involved in the above."

Solution:-

• At the point when an answer of potassium iodide is added to an answer of lead nitrate stepped through in an examination tube, the precipitation of a yellowish strong is noticed. This yellowish strong is lead iodide. Potassium nitrate is framed alongside lead iodide. This is a twofold relocation response.
• This is a double displacement reaction.
• $2KI(aq.)+Pb(NO_3_)2(aq.)\rightarrow 2KNO_3(aq.)+PbI_2(s)$.

Hence, the chemical reaction with potassium iodide is added to a solution of lead nitrate taken in test tube.
