Sample Questions on Precipitation Reaction
Question 1: Describe the solubility rules in precipitation reactions?
Answer:
Whether or not a reaction forms a precipitate is dictated by the solubility rules. The below mentioned are solubility rules:
- Nitrates (NO3-) salts are soluble.
- Salts formed with group 1 cations and (NH4+) salts are soluble.
- Bromides, chlorides, and iodides are soluble.
- Salts containing silver, lead, and mercury (I) are insoluble.
- Carbonates ( CO2−3), phosphates ( PO3−4), sulfides, oxides, and hydroxides ( OH−) are insoluble. Sulfides formed with group 2 cations and hydroxides formed with calcium, strontium, and barium are exceptions.
- Sulfates (SO2−4) are soluble with the exception of sulfates formed with Ca2+, Sr2+, and Ba2+.
Question 2: Does temperature affects the solubility in precipitation reaction?
Answer:
Yes, Temperature affects the solubility in precipitation reaction, If temperature is increased then it can increase the solubility of substances in precipitation reaction.
Question 3: How is KSP related to precipitate?
Answer:
KSP referred as a constant of solubility is a reaction equilibrium constant. If Solubility product is larger than the ionic product then no precipitate will form on adding more solute because unsaturated solution is formed.
Question 4: Why does an precipitation reactions occur in a solution?
Answer:
If a solution contains a particular cation (a positively charged ion) is combined with another solution containing a certain anion (a negatively charged ion), the formation of an insoluble compound can often occur. A precipitate is considered the solid that divides.so the precipitation reactions occur in a solution.
Precipitation Reaction
Precipitation Reaction is a chemical reaction in which dissolved substances react to form one or more solid products. Precipitation reactions help in identifying the presence of different ions present in a particular solution. In Precipitation Reaction, the ions of two different aqueous solutions react with each other to form an insoluble solid. This solid substance is called a precipitate and it settles at the bottom of the container. Precipitation acts as a major component in the water cycle and is responsible for depositing fresh water on the planet. Precipitation Reactions can be represented in chemical equations, which play an important role in various chemical processes. Students first read about Precipitation Reactions in Class 10.
In this article, we will learn about the Precipitation Reaction as well as the applications, Precipitation Reaction in Real Life, chemical reactions and also provide a step-by-step guide to help you easily understand Precipitation Reaction. So, let’s start with the definition of Precipitation Reaction.
