Question

Here,$X$ is a soluble salt which reacts with $NaOH$ to give a chalky white precipitate of $Pb{\left( {OH} \right)_2}$ . What is $X$ ?
 A.$Pb{\left( {N{O_3}} \right)_2}$
 B.$PbN{O_3}$
 C.$Pb$
 D.$PbN{O_2}$

Answer 1

Hint: We have to know that chemical reactions include substance changes that bring about the arrangement of new mixtures under some particular conditions. Chemical conditions can assist us with understanding the substance reactions between different components or mixtures. Compound conditions show the reactants and the items that are engaged with these reactions.

Complete answer:
We have to know that numerous chemical reactions happen in our day by day lives. Basic instances of such responses are consuming, erosion, preparing of food and assimilation. One significant class of substance responses are precipitation responses. In such reactions, two distinctive dissolvable salts (which are in watery arrangements) join to shape two items. One of these items is insoluble in the arrangement and is accelerated out.
The term precipitation reaction can be characterized as a substance reaction happening in a watery arrangement where two ionic bonds consolidate, bringing about the development of an insoluble salt. These insoluble salts shaped in precipitation responses are called accelerates. Precipitation responses are normally twofold uprooting reactions including the creation of a strong structure buildup called the accelerate.
All nitrate salts are solvent in water. $Pb{\left( {N{O_3}} \right)_2}$ is a solvent salt which responds with $NaOH$ to give white pale accelerate of $Pb{\left( {OH} \right)_2}$ .

Therefore, the correct option is (A).

Note:
We have to know that, the solid that structures by means of a precipitation response is known as hasten. Precipitation responses serve significant capacities. They are utilized for cleaning, eliminating or recuperating salts, for making colors, and to recognize substances in subjective investigation.
