Q.1. Name the following.
i. The product formed as a result of the reaction between sulphur dioxide and water.
ii. The gas produced when metals react with acids.
iii. The metal which does not react with dilute hydrochloric acid but reacts with sulphuric acid.
iv. The reaction between an acid and base to form salt and water.
Q.2. What is a displacement reaction?
Answers
Answer:
1) Sulfur-Based Reducing Agents
Sulfur dioxide (SO2) is a gas, formed by burning sulfur in air. When dissolved in water, SO2 forms sulfurous acid, a complex mixture of various hydrates of SO2 and the ions H3O+, S2O52 −, and HSO3−.
2) Hydrogen Gas
Acids react with most metals and, when they do, a salt is produced. But unlike the reaction between acids and bases, we do not get water. Instead we get hydrogen gas.
3) Copper
copper does not react with dilute hydrochloric acid even on heating but reacts with sulphuric acid .
4)The reaction of an acid with a base is called a neutralization reaction. The products of the reaction are a salt and water.
ques 2...
A single-displacement reaction, also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.
