Which one of the following does not result in the evolution of Hydrogen gas?
(a) Zinc and hydrochloric acid
(b) Aluminum and nitric acid
(c) Iron and sulphuric acid
(d) Magnesium and dilute nitric acid
Answers
Answer:
option b is correct option because nitric acid is a strong oxidising agent and only magnesium and manganese are the exceptions which can react with nitric acid to evolve hydrogen gas
Answer:
(d) Magnesium and dilute nitric acid does not result in the evolution of Hydrogen gas. This is because magnesium is not an active metal and does not react with dilute nitric acid. In other words, magnesium cannot displace hydrogen from dilute nitric acid.
Other active metals like iron, zinc, and aluminum can do so. When these metals react with dilute nitric acid, they displace the hydrogen, which then forms a gas. This gas is known as hydrogen gas, which is released as a result of the reaction between the active metals and diluted nitric acid. Thus, magnesium and dilute nitric acid do not result in the evolution of Hydrogen gas.
